    Dear mom:

    Congratulations on your order — the Mustangs Special is a great choice for your first seahorses!

    The care sheets and acclimation instructions for your Mustangs are available online at the following URL’s, and it would be a good idea for you to check it out before your seahorses arrive so you are familiar with the acclimation procedures and the needs of your seahorses when they are delivered:

    The acclimation instructions explaining just how to introduce your new seahorses to your aquarium are also available online, and it would be a good idea for you to review them at the following link

    In addition, I would be happy to discuss the acclimation procedures with you in greater detail and explain step-by-step exactly how to proceed. First of all, however, let me assure you that 9 times out of 10 the seahorses arrive in great shape without being unduly stressed by their long-distance shipping. And even in those rare instances when the seahorses do experience shipping stress and elevated ammonia levels while in transit, they almost always recover fully, none the worse for wear, within a short period provided they are acclimated properly. I know it’s hard not to get a little excited and nervous about your first seahorses, but you can be very confident that everything will go smoothly if you just follow the instructions.

    The following information should make everything crystal clear, as well as explaining why it is important to acclimate your new arrivals according to the instructions:

    Acclimating New Arrivals

    Acclimating newly arrived seahorses properly after their transoceanic, cross-country journey is absolutely vital. It’s not like acclimating the new specimens you bring home after a quick trip back from your local fish store. The long distances and prolonged transit times involved make proper care of the new arrivals once they finally reach you a far more urgent matter. The reason for this is that all the while the seahorses are en route, they are excreting wastes and respiring in the dark shipping box — consuming oxygen (O2) and giving off carbon dioxide (CO2). That means two things: deadly ammonia is steadily building up in the shipping bag and the pH is steadily dropping, making the water more acidic.

    This downward pH shift is actually helpful in that ammonia is less toxic at low pH and becomes much more toxic at higher pH. This is because ammonia exists in water in an equilibrium between two different forms — a nontoxic ionized form usually referred to as ammonium (NH4+) and an un-ionized form (NH3), which is highly toxic. Ammonium (NH4+) is completely harmless to fishes since the ionized ammonia molecule cannot cross the cell membrane and enter their cells. Note that only difference between harmless NH4+ and deadly NH3 is the addition of a hydrogen ion (H+), which converts toxic ammonia to nontoxic ammonium. At low pH, the extra hydrogen ions (H+) of acidic water are readily available to attach to the ammonia molecule, converting most of the ammonia to ammonium: NH3 + H+ —> NH4+. But at high pH, under alkaline conditions, exactly the opposite occurs. At high pH, the abundance of hydroxide ions (OH-) in alkaline water strips the extra hydrogen ion (H+) away from ammonium, rapidly converting most of it to deadly ammonia: OH- + NH4+ —> NH3 + H20. In other words, the higher (more alkaline) the pH, the more ammonia is present in the dangerous un-ionized form (NH3), which easily crosses cell membranes and enters the body.

    This should make it easier to understand exactly what is happening in the shipping bag. As the seahorses breathe, consuming O2 and giving off CO2, the pH of the water drops and more of the ammonia (NH3) they produce is assimilated into harmless ammonium (NH4+). So the decrease in pH that occurs during long-distance shipping is actually protecting the new arrivals somewhat — until we open the shipping bag! Once the shipping bag is opened, CO2 begins offgassing from the bag water and fresh O2 begins entering the water, and as the pH begins to rise in response and return to normal, the ammonia in the water becomes increasingly poisonous. And when we begin to add alkaline water with a pH of 8.0-8.4 from the main tank to the shipping bag, we are accelerating the pH shift and converting ever more of the ammonium (NH4+) to deadly ammonia (NH3). The suddenly high concentration of ammonia in the water quickly diffuses into the seahorse’s cells, and acclimating the new arrivals becomes a race against ammonia poisoning just that quickly.

    Acclimating farm-raised seahorses properly is therefore the art of achieving the proper balance between two conflicting needs: the need to get them out of the toxic shipping water as quickly as possible and the need to allow them to adjust to tank conditions as gradually as is practical. Drip acclimating the seahorses over a period of hours would expose them to dangerous ammonia levels for an extended period with harmful results, and adding an airline or otherwise aerating the seahorses in the shipping bag while they are acclimating, would likewise increase the levels of ammonia they were exposed to. If all goes well, it’s therefore important for the acclimation process to take no more than 20-30 minutes before your Ocean Riders are released into the main tank.

    Whereas drip acclimating is definitely the way to go when you bring home delicate invertebrates that are highly sensitive to water quality from your LFS, such as live corals, starfish, and decorative shrimp, it would actually be quite counterproductive for seahorses that have just arrived all the way from Hawaii.

    Here’s how to proceed:

    1) Open the shipping box away from any bright lights. Remember that seahorses don’t have eyelids — removing them from total darkness and suddenly plunging them in bright light can be very stressful! Darken the room lights and turn off the aquarium lights before you remove the shipping bags from the box.

    2) Float the unopened shipping bag(s) in your tank, or better yet in a clean container filled 2/3 of the way with water from the aquarium, for as long as necessary to equalize temperatures. (Those shipping bags can be dirty and germ laden!) In most cases, 10-15 minutes is all that’s necessary for the temperature adjustment, but during summertime heat waves or winter cold snaps it may take longer than that to equalize the temperature in the shipping bag with the aquarium water. As long as the shipping bags are unopened, you can take as much time as needed for this step of the acclimation process.

    3) Once the temperature has been equalized, partially open the shipping bag and check the parameters of the shipping water (temperature, salinity or specific gravity, and especially the pH). Compare those readings to the conditions in the destination tank. That will tell how you quickly you can proceed with the acclimation process. The specific gravity is not that critical at all. Seahorses tolerate a wide range of salinities and are very adaptable in that regard. If the water in the shipping bag and the water in the destination tank are equal in temperature, and within 0.1-0.2 of each other in pH, you may introduce the seahorses to the tank right away without the need for any further acclimation. If the temp or pH are slightly off, you can acclimate the seahorses to tank conditions in one or two steps, as described below. And if the temp, pH, or specific gravity is off considerably, you will need to adjust the seahorses to tank conditions carefully in three or more steps.

    4) The first of these steps is to add 1 cup of tank water to the shipping bag. Wait 10 minutes to allow the seahorses to adjust to any differences in tank water you just added.

    5) Do NOT aerate the shipping bag while you are waiting. I know it seems a helpful thing to do, and your first inclination will be to add an airstone or airline to the shipping bag, but that can have disastrous consequences! Aerating the shipping water will accelerate the upward shift in pH and hasten the conversion of harmless ammonium (NH4+) to toxic ammonia (NH3). Aerating the shipping bag during acclimation will thus put the new arrivals at grave risk from ammonia poisoning! Don’t do it.

    6) After 10 minutes have elapsed, remove 1 cup of water from the shipping bag and add another cup of water from the tank. Wait 10 minutes to allow the seahorses to adjust, and if they remain undistressed, repeat this procedure again. Judging from how great the initial discrepancy was in water quality parameters, this procedure can be repeated as often as necessary to adjust the seahorses to the tank conditions gradually, but try to complete the acclimation process within 30 minutes after the shipping bag was opened, if at all possible. In general, seahorses tolerate an accelerated acclimation procedure much better than prolonged exposure to ammonia in the shipping bag.

    7) Observe the new arrivals closely for any signs of ammonia poisoning throughout the acclimation process. The symptoms to look are a loss of equilibrium, hyperexcitability, increased respiration and oxygen uptake, and increased heart rate. At extreme ammonia levels, fish may experience convulsions, coma, and death. Seahorses exposed to less extreme ammonia levels will struggle to breathe. They will be lethargic and exhibit rapid respiration. They may appear disoriented, periodically detaching from their hitching posts only to sink to the bottom. Don’t panic at the first sign of rapid breathing, but if you detect any of the more serious symptoms of ammonia toxicity, stop acclimating and get the seahorses into the destination tank immediately! Don’t hesitate! Your seahorses will tolerate an emergency transfer far better than they can withstand prolonged exposure to high levels of deadly ammonia in the shipping bag.

    8) If all goes well, you can release the seahorses into the destination tank at your leisure following a 2- or 3-step acclimation process. I do not like to use an aquarium net to transfer seahorses, since their delicate fins and snouts can become entangled in the netting all too easily. I much prefer to transfer the seahorses by hand. Simply wet your hand and fingers (to avoid removing any of the seahorse’s protective slime coat) and scoop the seahorses in your hand. Allow them to curl their tail around your fingers and carefully cup their bodies in your hand to support them while you lift them out of the water. When you gently immerse your hand in the destination tank, the seahorse will release its grip and swim away as though nothing out of the ordinary has happened. Take care to get as little of the noxious water from the shipping bags as possible into the aquarium when you transfer the seahorses. Discard the impure shipping water when you are finished.

    9) Leave the aquarium light off and let the seahorses settle down and adjust to their strange new surroundings at their own speed. Don’t attempt to feed them for the first day. Just give them plenty of room and allow them to settle in and investigate their new home in peace and quiet. Admire them from afar. The next morning you can turn on the aquarium light at the usual time and offer them their first meal.

    Don’t let the discussion of ammonia poisoning and shipping stress above worry you. It’s not meant to alarm you in the least, only to explain why it’s important to complete the acclimation procedure quickly (which is why drip acclimating the seahorses is counterproductive and could even be harmful) and what to do in the extremely unlikely event an emergency should arise during acclimation. Ocean Rider stresses the proper acclimation procedure because they have occasionally had a problem in the past with experienced aquarists who felt they knew better and disregarded the acclimation instructions in favor of drip acclimation or a more prolonged process, to the detriment of their new arrivals. In all probability, your seahorses will arrive in excellent condition and not stressed out in the least, and even when shipping stress is a factor, the seahorses typically recover quickly and are back to normal by the following day.

    Best wishes with all your fishes, mom! I know you are really going to enjoy your new Mustangs!

    Happy Trails!

    My guys are here – they are beautiful – red – huge 🙂 – at least compared to the others I had before- kinda stressed out but seem ok – I will leave the lights out all day – they are exlporing a bit – latching on –

    my daughter named them Max and Ruby – the male is the one with the rounded belly right ?

    Dear mom:

    I am happy to hear that your new seahorses are big and beautiful and seem to be settling in nicely. It sounds like you did a good job of acclimating them to their new home.

    Yes, that’s right — it’s best to leave the aquarium light off for the first day and give the new arrivals plenty of peace and quiet while they are making the adjustment to their strange new surroundings. Tomorrow you can turn the aquarium light on, as usual, and try feeding your new acquisitions for the first time.

    Yup, when you are sexing seahorses, there is indeed a noticeable difference in the profile of the abdomen. In females, the abdomen curves inward more sharply, so that the base of the belly almost forms a right angle to the tail. In males, the abdomen slopes inward toward the tail more gently, giving the base of the belly a more rounded appearance in profile. It is the presence of the pouch or marsupium in the males that accounts for the difference in their silhouettes.

    Sexing adult, fully mature seahorses in breeding condition is therefore normally simple and straightforward — the males have a brood pouch slung under their abdomens at the base of their tails and the females do not. This difference will be most obvious when the seahorses are courting and breeding, since the stallions perform vigorous pouch displays in which they inflate their pouches with water to the bursting point, making them unmistakable.

    Best of luck with Max and Ruby, mom!

    Happy Trails!

    My male does not seem to be eating – I have seen the female eat – he is still mostly hanging out in one spot – is that normal? Granted I have only had them since Wed –

    Is the 20 gallon tank big enough? it is not a tall – should I move them to my 55 once I get it cycled (which will be a bit- just changed it over from fresh water- only live sand in it right now – going to put live rock in soon)

    oh I also accidentally let a fair amount of shipping water go into the tank – should I do a partial water change?

    Dear mom:

    You needn’t be concerned that your new male hasn’t shown an interest in the frozen Mysis if it has only been a short period since he was introduced to your aquarium. That’s pretty normal, mom — it sometimes takes new arrivals a week or two to recover from the stress of long-distance shipping and get adjusted to their strange, new surroundings before they begin to feel at home and resume feeding on the frozen Mysis as usual. That’s why it’s customary to provide a small supply of the red feeder shrimp when you order seahorses — to help ease their transition into their new environment and keep them well-fed while they make that adjustment. Just be patient and I’m sure the male will be scarfing up the frozen Mysis along side of his mate before you know it.

    No is it at all unusual for a stallion to be more sedentary than his mate, especially when he’s still uncertain if his new surroundings are entirely safe or not. It is normal for male seahorses to be somewhat less active than the females. Males tend to be real homebodies that will often choose one particular hitching post as their home base and spend much of there time perched right there (think of your Dad hunkered down in his favorite easy chair in the den). Researchers studying seahorses in the field therefore refer to males as "site-specific" because they can be found at the same tiny patch of reef or coral formation or seagrass day after day, rarely straying from their chosen spot. Mature males are often naturally more shy and retiring than females, which can be quite brazen at times. I suspect this is due to their parental duties — during the breeding season, pair-bonded males are ordinarily ALWAYS pregnant, and they can’t risk exposing their precious cargo to any more risk than absolutely necessary.) The unfettered females tend to be far more footloose and fancy free, and in the wild they typically roam over a home territory of up to 100 square meters. So I wouldn’t worry if your male only tends to wander around the tank on occasion, whereas your female is more active and explores more. As long as he is breathing normally, at about the same rate as the female, I don’t think you have anything to worry about.

    Yes, I think that’s an excellent idea to upgrade your seahorse tank from a 20-gallon to your 55-gallon aquarium as soon as it has cycled and the biological filtration is fully established. A standard 20-gallon aquarium is not tall enough to assure the long-term health of your seahorses, and the larger volume of water in the 55-gallon tank will keep the conditions much more stable and provide you with a much greater margin for error.

    Here are our usual Club feeding tips, including suggestions on feeding new arrivals (tip #2), in case you haven’t already seen them, mom. They should give you a better idea about how to proceed when feeding your new ponies and coaxing the reluctant male to eat:

    Feeding Tips

    In addition to cycling your aquarium and setting it up to create an ideal environment for seahorses, you will also need to line up a good source of frozen Mysis before your seahorses arrive. Frozen Mysis is available in several different brands from many different sources. Gamma brand frozen Mysis is good, Hikari frozen Mysis is quite acceptable (although often fragmentary) as is San Francisco Bay brand frozen Mysis, the Mini Mysis by H2O Life is great for small seahorses, and Piscine Energetics frozen Mysis is no doubt the best in terms of nutritional content and quality control. Your local fish stores should carry one or more of these brands.

    I have noticed that seahorses can sometimes be very selective when it comes to the size of the prey they prefer. For instance, the jumbo PE Mysis relicta are of course quite large, and in it’s certainly possible that young seahorses may balk at the jumbos simply because of their size.

    Fortunately, the Piscine Energetics frozen Mysis relicta is now available graded for size. You can get the usual jumbo Mysis relicta or smaller Mysis and young (i.e., small) seahorses sometimes prefer smaller prey and do better with the smalls. Some seahorses are very particular in that regard, and tend to reject food items that are significantly larger or smaller than their preferred range of prey. For example, I’ve seen some seahorses that rejected the smaller Hikari Mysis with great disdain, yet which greedily gulped down the jumbo Piscine Energetics Mysis relicta. On the other hand, I’ve had small seahorses turn up their snouts at the jumbo PE frozen Mysis because it’s too large for their liking, and attack the small Hikari frozen Mysis with great gusto.

    Whatever brand of frozen Mysis you obtain, for best results, it’s a good idea to fortify it with Vibrance before feeding it to your seahorses. Vibrance is an enrichment formulation that was designed by a research team of nutritionists and fish biologists especially for use with frozen Mysis shrimp in order to meet the dietary requirements of seahorses, and it has been developed specifically to provide a long-term balanced diet for these unique fishes. depending on which Vibrance formulation you use, it includes additional highly unsaturated fatty acids (especially the DHA Omega 6 DHA series), along with Vitamin C and essential minerals, in the proper proportions to further enhance the nutritional profile of the protein-rich frozen Mysis. Studies indicate the DHA it includes is essential for high survivability, nerve development, stress management, and proper reproduction. Vibrance is a bright red-orange powder that gets its characteristic color due to its high content of carotenoids, which are an abundant source of Vitamin A and act as natural color enhancers for yellow and red pigmentation. It is the only enrichment product that includes beta glucan as an active ingredient. That’s important because beta glucan is a potent immunostimulant that provides important health benefits for fish.

    In order to enrich it, the frozen Mysis is carefully thawed out and rinsed well to remove any excess shrimp juices, and then a VERY light dusting of the Vibrance is added to the Mysis while they are still just a bit moist. The Vibrance is then gently worked into the frozen Mysis and it usually adheres very well. The end result should be whole, completely intact Mysis shrimp that have acquired a reddish tinge to their head or anterior end. In actual practice, there are probably as many different ways of successfully thawing and enriching frozen Mysis as there are aquarists that use them; most everybody works out their own method of preparing the frozen Mysis that works best for their needs and busy schedule.

    In case you haven’t seen them already, here are the Club’s usual feeding tips, mom, including suggestions for feeding new arrivals (Tip #2):

    Feeding Tips

    In general, it’s a good idea to offer one morning feeding and one mid-to-late afternoon feeding, if possible, but there are no hard-and-fast rules when it comes to easy-to-feed, farm-raised horses. Some hobbyist prefer to give their seahorses two feedings a day, while others prefer to give them their quota of frozen Mysis in one big meal. As long as they get their fill, there is really no right or wrong way to go about this — just do whatever works bests for your seahorses and your schedule.

    As you know, the feeding regimen that generally works best for most captive-bred seahorses is to provide each of them with 2-7 frozen Mysis relicta twice a day, enriched with Vibrance, and then to fast your seahorses entirely once a week. In other words, your seahorses should each be eating a total of around 4-14 frozen Mysis each day, depending on the size of the seahorse and the size of the Mysis. But those are just rough guidelines and there is a lot of variation in how much Mysis healthy seahorses eat each day.

    A large seahorse naturally eats more than a smaller pony. And jumbo-sized Mysis will fill up a hungry seahorse faster than smaller shrimp. So a seahorse that’s scarfing up king-sized Piscine Energetics Mysis relicta does indeed need to eat fewer shrimp than a pony that’s dining on the tiny Hikari Mysis or the miniscule H2O Mini Mysis.

    Aside from size, some of the other factors that determine how much a seahorse eats are water temperature, the age of the seahorse, and whether or not it is actively breeding at the moment. The warmer the water temperature (within the seahorse’s comfort zone), the higher it’s metabolism, and the more calories it needs to eat as a result. Young seahorses that are still growing rapidly typically eat more than mature seahorses that have reached their full growth. As you might expect, breeding pairs that are producing brood after brood every few weeks need to eat a lot because so much of their bodily resources go towards producing clutches of eggs or nourishing a pouch full of developing young.

    So don’t get hung up trying to count every morsel every seahorse in your tank scarfs down. Just make sure all your seahorses have full bellies at the end of the day, as indicated by their well-rounded abdomens. After a good feeding, the seahorses belly rings should be flush or even slightly convex in cross section when viewed from head on. (We never want to see sunken, severely pinched-in abdomens on our seahorses! Concave belly rings are a sure sign of an underfed seahorse, with the sole exception of a female that has just transferred her eggs.)

    So if you want to check whether your seahorses are eating well or not, don’t look at their profile — just examine them head-on and check out their gut. Their abdomens or belly plates should bulge out slightly or at least be flush with their flanks, not pinched in or sunken. In other words, when viewed from the back or from head-on, the cross-section of their abdomens should appear concave "( )" or flush "l l" rather than concave ") (" or pinched in.

    Feeding Frozen Mysis

    (1) Tips for thawing and enriching frozen Mysis.
    In order to prevent wastage and obtain the maximum benefit from this superb food, it must be thawed properly. This is especially important because once the Mysis are fully thawed, they are not refreezable (Adib, 2004). Most hobbyists tend to simply thaw their mysids in aquarium water, which has the virtue of thawing it quickly but is not the best approach. The faster the frozen shrimp is thawed, the more likely it is to be damaged in the process. We want the mysids to remain intact and lifelike; we don’t want the tissue of the Mysis to begin to breakdown in the process of freezing/thawing. The goal is to preserve the Mysis and retain all those precious shrimp juices when we thaw it, not to release their fluids into the aquarium water where it will only degrade the water quality and do your seahorses no good!
    So don’t thaw frozen Mysis in 75°F-80°F aquarium water. Don’t nuke it in the microwave to defrost it! And don’t simply toss a chunk of frozen Mysis in your tank and let it float around until it thaws and releases individual mysids!
    Nor should you thaw it in tap water, distilled water, or any other source of freshwater. You want to thaw the shrimp in water that is about as salty as their own bodily fluids so there is little or no difference in osmotic pressure. Freshwater will tend to move into the mysids as they thaw and can break down their integument and rupture cell walls as they swell; excessively salty water will tend to draw water out of the Mysis as they thaw, desiccating them in the process. Normal strength seawater is just right for thawing.
    So the recommended method for thawing frozen Mysis is to use refrigerated saltwater from your aquarium. Keep a small jug of your artificial saltwater in your refrigerator and reserve this for thawing your mysids (Adib, 2004). Place a couple of ounces of the chilled saltwater in a small cup or similar receptacle and use that to thaw the shrimp. Break off a small chunk from the mass of frozen Mysis — just enough for one feeding or a day’s worth at most (with experience, you will soon learn exactly how much to use) — place it in the cup of saltwater and allow the Mysis to slowly thaw in the refrigerator for 30-45 minutes (Adib, 2004). Then take the cup out of the refrigerator and allow the thawed Mysis to warm up at room temperate for another 15 minutes (Adib, 2004). This method leaves the mysids perfectly intact and lifelike, and produces immaculate shrimp that need no further rinsing. (If you use another method for thawing the Mysis, it’s generally advisable to rinse the thawed shrimp in a brine shrimp net to prevent fouling of the aquarium water.) You are now ready to fortify the Mysis with the enrichment formula of your choice.
    Carefully remove the individual thawed mysids from the thawing container using a plastic fork or a toothpick and gently deposit them in the bowl of a plastic spoon. The idea is to handle the shrimp as little as possible during the thawing and enriching process, since rough handling can cause the mysids to break apart. If your enrichment product is in powder form such as Vibrance (which I recommend), take a pinch of the formula, sprinkle it on the Mysis, and mix it in very gently (a plastic knife or similar instrument works well for this step). The orange power will adhere to the moist Mysis, and when you’re done, the head region (cephalothorax) of the mysids should be stained reddish. (If your preferred supplement is a liquid formula, just add a few drops to the Mysis and let it soak in.)
    With a little practice, most hobbyists quickly work out their own technique for preparing enriched Mysis. The method outlined above works well for me and many other aquarists, but there are many other ways of defrosting and enriching the Mysis that work equally well. For instance, other hobbyists prefer to add a dusting of enrichment powder (or a few drops of a liquid supplement) to a chunk of frozen Mysis and gently mix it in (or allow it to soak in) as it thaws. One nifty way to do this is to break off my little chunk of frozen shrimp and place it on a square of wax paper, allow it a while to defrost, and then add a pinch of enrichment formula and roll the Mysis and power in the wax paper as though making a cigarette. This technique is trickier and takes a little experience before you can pull it off properly. The thawing and rolling/mixing process must be done very, very carefully or you may crush some of the Mysis and lose a lot of shrimp juice while preparing it. As always, if you’re doing it right, the heads of the individual Mysis shrimp should end up stained red, which is a feeding "trigger" captive-bred chowhounds find hard to resist. With a little practice, you will soon refine your own method for preparing frozen Mysis that works the best for your schedule and the needs of your herd.
    But however you prepare it, it’s important to keep the enriched Mysis refrigerated until it’s used, and to use all the Mysis you thawed and enriched within 24 hours. For best results, the enriched Mysis should be used immediately after it’s prepared. Whether it’s been refrigerated or not, avoid using thawed and prepared Mysis that is 2 or 3 days old. We don’t want to offer our seahorses food that might have become laden with bacteria.

    (2) When it comes to feeding, give new arrivals time to recover and settle into their new surroundings before you force the issue.
    That’s a long haul from Hawaii, and it sometimes take new arrivals a good week or two to settle in, make themselves at home, and start feeding normally afterwards. For that reason, I suggest the hobbyist have a supply of live food on hand whenever acclimating new additions to his herd. The tiny red feeder shrimp from Hawaii (Halocaridina rubra) are ideal for this, but live Gammarus, ghost shrimp, or even adult brine shrimp will do. The live shrimp help them adjust during the initial acclimation period when you first introduce your seahorses to your tank. The live foods will give the new arrivals a head start, help them recover from shipping stress quickly, and get them through the difficult period of adjustment in tiptop condition.
    Don’t worry about feeding your seahorses immediately after they arrive. Give them a good 24 hours to adjust and settle down first. After the adjustment period, go ahead and offer some carefully thawed Mysis to your seahorses each day. Many seahorses handle shipping and acclimation with ease and never miss a beat, gobbling up frozen Mysis from Day One. Others will need more time before they feel at home in their new surroundings, and may not feel comfortable enough to accept frozen Mysis from their keeper until a week or two has passed. So keep offering Mysis each day, but feed it sparingly at first and remove any uneaten Mysis after an hour or so. Once the seahorses that start eating the Mysis first have had their fill, add some live feeder shrimp for the others that are lagging behind.
    Many times all the seahorses resume feeding on the frozen Mysis right away and the live red feeder shrimp aren’t needed; in that case, simply keep them on hand for use as occasional treats. They last indefinitely in a clean, aerated plastic bucket at room temperature with a pinch of flake food sprinkled in sparingly a few times a week.
    Be patient with the ones that seem more reluctant to resume feeding on frozen Mysis. Don’t isolate them from the others, don’t pester them by persistently trying to target feed them at this point, and don’t keep dropping frozen shrimp on their heads! That can spook a high-strung seahorse and stress him out all the more, setting him back further. Just give them time and they will soon join the others, scarfing down frozen Mysis greedily again. This can sometimes take a couple of weeks. (Mature males often lag behind at first; for some reason, they seem to be more shy and retiring than females, which can be quite brazen at times. I suspect this is due to their parental duties — during the breeding season, pair-bonded males are ordinarily ALWAYS pregnant, and they can’t risk exposing their precious cargo to any more risk than absolutely necessary.) Make a note of the reluctant eaters; the ones that are slow to take frozen Mysis now may require target feeding later on.

    (3) Be aware of secretive feeders and give them plenty of room at first.
    It’s quite common for new arrivals to display shy, secretive behavior. I have found that some of my seahorses, especially newly acquired specimens, are reluctant to eat while they know they are being observed. That doesn’t mean they are starving themselves, however, just that they tend to feed in secret. Rather than feeding from your hand or gobbling up the Mysis when you first offer it, they will prey upon the natural fauna in the tank, slurping up copepods and amphipods from hiding, or snatch up leftover frozen Mysis when they think no one is looking. Some of the seahorses that don’t appear to be eating at first may actually be feeding on the sly.
    When that’s the case, it’s best to back off a bit and leave the tank alone as much as possible for the time being. It’s okay to observe the tank discretely but try to avoid flat-nose syndrome, and keep feeding your other specimens as usual, of course, but don’t try to force the issue with the shy ones. Just leave them be, give the seahorses plenty of peace and quiet, and let the secretive feeders adjust to their new environment and get used to the daily routine at their own speed. Before too long, they’ll begin sneaking leftover Mysis when they think you’re not watching and feel safe. Once they feel at home, the shy specimens will start exploring their tank freely and displaying themselves openly. Before you know it, they’ll come to recognize you as their feeder and begin interacting with you at dinnertime. And from there, it’s just one short step until you have them literally eating from your fingers.

    (4) Morning feedings are best.
    The recommended feeding regimen is to provide each of your seahorses with 4-14 frozen Mysis shrimp daily, enriched with a good food supplement, and then to fast your seahorses entirely once a week. Some hobbyist prefer to give their seahorses two feedings a day, while others prefer to give them their quota of frozen Mysis in one big meal. As long as they get their fill, there is really no right or wrong way to go about this — just do whatever works bests for your seahorses and your schedule.
    However, many hobbyists find that their seahorses feed best during the morning, so if you can only feed your seahorses once a day, try to make it a morning meal. Whether it’s their biological clocks, something built into their natural circadian rhythm, or whether they’re simply hungriest shortly after waking up, seahorses do seem to feed more aggressively in the morning, and hobbyists should try to accommodate them, if possible. Breakfast, it seems, is the most important meal of the day for our aquatic equines as well as ourselves.
    If you can only manage one feeding a day, DO NOT make it an evening meal. The worst thing you can do is to feed your seahorses late in the day when there will likely still be leftovers remaining at lights out. The uneaten Mysis will begin decaying overnight and put your water quality at risk. Worse still, the next morning, when they are hungriest, your seahorses may discover the bacteria-laden Mysis and snap them up off the bottom. This is an excellent way to spread disease and make your seahorses sick. Feeding your seahorses early in the day, so they have plenty of time to clean up leftovers, is a good way to prevent this. An efficient clean-up crew of scavengers also helps.

    (5) Use a feeding station.
    Seahorses respond very well when they are fed at the same time and place each day. They quickly learn the routine and will come to recognize their keeper as the one who feeds them — the giver of gourmet delights! Once that happens, they will often beat you to the spot, gathering around their feeding station as soon as they see you approach.
    In fact, the aquarist can easily condition his seahorses to come a running at feeding time. Before you open the aquarium cover, make a point of lightly tapping it a few times or rapping on it gently. The seahorses will quickly learn to associate the tapping with the mouthwatering morsels that follow, and before you know it, they will respond by gathering at the feeding station as if you were ringing the dinner bell.
    To facilitate this process and make feeding them easier, choose a feeding station that’s convenient for you in a relatively uncluttered part of the aquarium, and give your seahorses their meal right there every day. The feeding station should have some convenient hitching posts situated nearby as well. Avoid using an area where currents might whisk the food away from the seahorses before they can eat it.
    I know one hobbyist who uses a toadstool leather coral as his feeding station. He places the Mysis on the bowl-shaped top of the toadstool, which contains them nicely while his seahorses perch around the edges and scarf up the shrimp as if dining at a lunch counter.
    Not everyone has a toadstool coral to serve as a natural feeding station, of course, but it’s easy to make your own lunch counter that will work just as well. Get a small Pyrex bowl or a similar shallow container made of clear glass or plastic (a large petri dish works great for this) and fill it about halfway with your tank substrate (Mike Kelly, pers. com.). Then sink the bowl into your sand bed until the substrate you placed in the bowl is level with the substrate in the tank (Mike Kelly, pers. com.). Leave the rim sticking up above the sand bed about a 1/2 to 3/4 of an inch or so (Mike Kelly, pers. com.). The clear glass rim of the bowl is transparent and virtually unnoticeable, so don’t worry that it will detract from the appearance of your display tank. Artfully position a few natural hitching posts around the bowl to provide your seahorses with a handy perch from which to snick up their dinner.
    At feeding time, place the frozen Mysis on the sand or gravel inside the bowl. A long tube of clear plastic 1/2′ to 1′ in diameter facilitates this. The bottom of the tube is placed in the middle of the bowl and the enriched Mysis are then placed in the top of the tube, which guides them exactly where you want them as they sink. The rim sticking above the sand bed will then keep the food in place while your seahorses dine at their leisure. Afterwards, any leftovers are neatly contained, making cleanup a breeze!
    Or you can always purchase a seahorse feeding station off the shelf, ready to go, as is. Artificial cup coral makes an attractive elevated "lunch counter" that does the job nicely. Elevated on a pedestal, the seahorses can perch around the edge of the cup, which contains the frozen shrimp nicely until eaten. The coral cups are very lifelike and make nifty ready-made feeding stations if positioned at a convenient (for you and your galloping gourmets) spot in your tank where currents won’t whisk the Mysis away.
    Another handy item that makes a great ready-made feeding station for seahorses are the conical worm feeders designed for offering bloodworms and tubifex worms to fish. They may require a little modifying since many of them are designed to float. Depending on the type of feeder, you may have to perforate air filled chambers around the collar, weigh it down to submerge it, or cut the conical worm trap free from the rest of the feeder. Worm feeders come with a suction cup, so once you’ve overcome the buoyancy problem, they can be secured anywhere in the aquarium you want, and they work just as well with frozen Mysis as with worms. If you position the conical feeder where a slight current hits it, gently jostling and agitating the frozen Mysis inside, it is even more effective. The flow of water imparts a bit of movement to the frozen Mysis, causing it to twitch or swirl about just a bit periodically inside the feeder. This makes the thawed Mysis look all the more lifelike and quickly attracts the interest of the seahorses. They will gather around the feeder and snick up Mysis through the open top. The conical shape of these feeders contains the frozen Mysis even better than most other feeding stations.
    Some hobbyists prefer a more natural looking, aesthetically pleasing feeding station, which they fashion themselves to suit their own tastes. They start with a piece of well-cured live rock that’s approximately the right size and shape, and painstakingly hollow out the center to form a shallow concave depression. This shallow bowl is fashioned by grinding it out, using an electrical moto-tool (available at any craft store or hardware store) with a carbide burr or sometimes even a shop grinder. Once the bowl has been hollowed out, a series of holes are then drilled around the circumference of this depression. Red, brown or purple Gracilaria, green Caulerpa and/or gorgonian branches are planted in these holes to create natural hitching posts. As the macroalgae takes hold and fills out, this produces an attractive feeding station that looks completely natural. It’s a great do-it-yourself project for the handy hobbyist.
    An upturned clamshell also makes a nifty natural feeding station that fits in perfectly in your seahorses’ setup. Choose a colorful natural seashell for this, such as one valve of a Tridacna clam or perhaps a Lion’s Paw Scallop shell, and you have an attractive feeding station that’s perfectly appropriate for your tank. The concave interior of the bivalve shell acts as a shallow bowl to contain the frozen Mysis until it’s eaten, and unlike some feeding stations that look out of place and detract from the appearance of your tank, a seashell looks as natural as can be in a marine aquarium. My favorite for this type of feeding station is a medium-sized Abalone shell. The iridescent, opalescent colors of the upturned interior, with its magnificent polished surface of mother-of-pearl, are spectacular! An upturned abalone shell requires no further modification whatsoever, making it the ideal feeding station for the unhandy hobbyist who’s all thumbs.
    Other aquarists reserve a small, transparent glass bowl or clear plastic receptacle for feeding their seahorses. They merely place the bowl or plastic container on the bottom of the tank at feeding time, add the enriched Mysis, and let their seahorses gather round and dine at their leisure as though eating from a feeding trough. A few hours later, the feeding container is removed, along with any leftovers. Quick and easy!
    For more information, see my article in Conscientious Aquarist which explains exactly how to set up a feeding station and train your seahorses to use a in greater detail.. It’s available online at the following URL:

    (6) Target feed your seahorses and remove uneaten leftovers promptly.
    The individual personalities of seahorses naturally extend to their feeding habits. Some are aggressive feeders that will boldly snatch food from your fingers, while some are shy and secretive, feeding only when they think they’re not being observed. Some like to slurp up Mysis while it’s swirling through the water column, and some will only take Mysis off the bottom of the tank. Some are voracious pigs that greedily scarf up everything in sight, and some are slow, deliberate feeders that painstakingly examine every morsel of Mysis before they accept or reject it. Some eat like horses and some eat like birds. So how does the seahorse keeper make sure all his charges are getting enough to eat at mealtime? How does the hobbyist keep the aggressive eaters from scarfing up all the mouth-watering Mysis before the slower feeders get their fair share? And how can you keep active fishes and inverts with seahorses without the faster fishes gobbling up all the goodies before the slowpoke seahorses can grab a mouthful?
    Target feeding is the answer. Target feeding just means offering a single piece of Mysis to one particular seahorse, and then watching to see whether or not the ‘horse you targeted actually eats the shrimp. Feeding each of your seahorses in turn that way makes it easy to keep track of exactly how much each of your specimens is eating.
    There are many different ways to target feed seahorses. Most methods involve using a long utensil of some sort to wave the Mysis temptingly in front of the chosen seahorse; once you’re sure this has attracted his interest, the Mysis is released so it drifts down enticingly right before the seahorse’s snout. Most of the time, the seahorse will snatch it up as it drifts by or snap it up as soon as it hits the bottom.
    A great number of utensils work well for target feeding. I’ve seen hobbyists use everything from chopsticks to extra long tweezers and hemostats or forceps to homemade pipettes fashioned from a length of rigid plastic tubing. As for myself, I prefer handfeeding when I target feed a particular seahorse.
    But no doubt the all-time favorite implement for target feeding seahorses is the old-fashioned turkey baster. The old-fashioned ones with the glass barrels work best because the seahorses can see the Mysis inside the baster all the way as it moves down the barrel and out the tip. By exerting just the right amount of pressure on the bulb, great precision is possible when target feeding with a turkey baster. By squeezing and releasing the bulb ever so slightly, a skillful target feeder can keep a piece of Mysis dancing at the very tip of the baster indefinitely, and hold the tempting morsel right in front of the seahorse’s mouth as long as necessary. Or if the seahorse rejects the Mysis the first time it drifts by, a baster makes it easy to deftly suck up the shrimp from the bottom so it can be offered to the target again. In the same way, the baster makes it a simple matter to clean any remaining leftovers after a feeding session. (You’ll quickly discover the feeding tube is also indispensable for tapping away pesky fish and invertebrates that threaten to steal the tempting tidbit before an indecisive seahorse can snatch it up. And it’s great for tapping on the cover to ringing the dinner bell and summon the diners for their gourmet feast!)
    In short, target feeding allows the hobbyist to assure that each of his seahorses gets enough to eat without overfeeding or underfeeding the tank. And it makes it possible to keep seahorses in a community tank with more active fishes that would ordinarily out-compete them for food, since the aquarist can personally deliver each mouthful to the seahorses while keeping more aggressive specimens at bay.
    The key to keeping active specimens like firefish or compatible clownfish or cleaner shrimp successfully with seahorses is to feed the other fish and inverts with standard, off-the-shelf aquarium foods first, and once they’ve had their fill, then target feed the seahorses.

    (7) If possible, stick with frozen Mysis relicta from Canada.
    Although there are several types of frozen Mysis on the market, the deep, cold water habitat and the unique way its captured and prepared makes Mysis relicta far superior to the others for feeding seahorses due to a variety of reasons (nutritional value, each individual shrimp is frozen whole and intact, the most lifelike in appearance, natural odor attractants, etc.). The fatty acid profiles of Mysis relicta are higher than that of enriched brine shrimp and it has more than three times the fatty acid content of ocean krill (Piscine Energetics. 2003). These high levels of fatty acids not only provide seahorses with essential nutrition, but also stimulate a positive feeding response (Piscine Energetics. 2003). Mysis relicta are high in protein and high in animal fat, yet are sodium free. The lack of salt intake is desirable for marine fishes, which are constantly working to expel salt from their bodies (Piscine Energetics. 2003). Suffice it to say that almost all farm-raised seahorses are pretrained to eat frozen Mysis relicta, and that’s the species they will eat the best in the hobbyist’s home aquarium as well.
    One big reason for this is Mysis relicta’s highly diversified eating habits. The food chain in the deep, cold waters that this species prefers gives it extremely high levels of EPA and DHA (fatty acids), which are not only important for the nutrition they provide, but also act as natural appetite stimulants, triggering a positive feeding response in seahorses (Piscine Energetics. 2003).
    Another reason Mysis relicta is eaten so greedily by seahorses is that it is virtually identical in appearance to the mysids that are a favorite food of all Syngnathids in the wild. Equally important, the Mysis relicta are flash-frozen after harvesting while they are still alive and kicking (Piscine Energetics. 2003). Their lifelike appearance is thus perfectly preserved, and they reach the consumer as whole intact shrimp. This is very important because seahorses accept frozen shrimp much more readily when the eyes and head are intact. I have observed on many occasions that when frozen Mysis are broken and fragmented, as is common with some brands, the seahorses will often eat the anterior portion with the eyes and antennae still present, and totally ignore the rest of the parts. Needless to say, that’s not only wasteful but also bad for your water quality. Mysis relicta thaws as whole, intact, individual shrimp, preventing such problems.
    In short, Piscine Energetics frozen Mysis relicta has a superior nutritional profile and is a very desirable food source for large seahorses and other marine fish. But the PE frozen Mysis is by no means a prerequisite for keeping Ocean Rider seahorses. If you find the PE Mysis difficult to obtain locally, your seahorses will be quite content with another good brand of frozen Mysis that is readily available in your area. In fact, young seahorses often prefer the smaller Hikari frozen Mysis until they have grown large enough to handle the jumbo PE frozen Mysis.
    I normally obtain my PE frozen Mysis from Premium Aquatics because they offer it online in small quantities, and they offer it graded for size (when they have it in stock, you can obtain either small Piscine Energetics Mysis relicta or the usual king-sized PE Mysis relicta).
    If you want to go with the PE Mysis relicta, you can order it online from Premium Aquatics (see link below).

    Click here: Frozen Foods: Premium Aquatics
    http://www.premiumaquatics.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=Mysis

    If Premium Aquatics is out of the PE Mysis relicta, which happens at certain times of year, your next best bet is to contact Piscine Energetics and obtain a list of the retail outlets that carry their Mysis relicta, as Leslie explained. Depending on where you live, you may be able to obtain the PE Mysis relicta from a local fish store in your area:

    Click here: Mysis Relicta — Natural fish food,for finicky saltwater and freshwater fish, by Piscine Energetics
    http://www.mysis.com/about.html

    If piscine energetics frozen Mysis relicta proves to be difficult to obtain in your area, frozen Mysis is available in several different brands from many different sources, and one of the other brands will suffice. Gamma brand frozen Mysis is good, Hikari frozen Mysis is quite acceptable as is San Francisco Bay brand frozen Mysis, and Piscine Energetics frozen Mysis is, of course, perhaps the best in terms of nutritional content and quality control. Your local fish stores should carry one or more of these brands. One way or another, you need to line up a good source of frozen Mysis to serve as the staple, everyday diet for your domesticated seahorses.

    (8) Observe fast days and don’t overfeed.
    One of the most common mistakes hobbyists make is to overfeed their seahorses. Any excess Mysis that’s not eaten within an hour or two of a feeding can become a threat to your seahorses. Either it will find its way into some inaccessible nook of the aquarium and begin to decay, degrading your water quality, or it may be noticed by a hungry seahorses hours later or perhaps even the next day, and eaten after bacteria have gone to work on it. The best way to avoid such problems is to target feed and remove leftovers promptly, as soon as you’re sure all the seahorses have had their fill. If you can only feed once a day, make it a morning meal before you leave for work, so the seahorses have the rest of the day to glean their leftovers. A good cleanup crew can also help by taking care of any uneaten morsels that slip past the aquarist.
    It’s equally important to observe the once-a-week fast day. Fasting helps prevent any potential problems with hepatic lipidosis (fatty liver disease) and keeps your seahorses feeding aggressively rather than losing interest in frozen foods. The problem is that although fasting is very healthy for seahorses on a staple diet of enriched Mysis, it can be very hard on the hobbyist. Here’s how I described this dilemma in a recent aquarium magazine article (Giwojna, Jun. 2002):
    "The only thing I don’t like about this extremely nutritious diet is the obligatory fast day. The problem with fasting is that my mustangs don’t seem to realize it’s good for them — that it’s absolutely in their own best interests, essential for their long-term health. Whenever I make an appearance on fast day, they insist on parading back and forth in front of the glass in their greeting colors, begging for a handout. Before my butt hits the upholstery, both of them will be dancing at the feeding station, impatiently awaiting their gourmet shrimp dinner. When it doesn’t materialize, they forlornly abandon their post at the lunch counter, and come up to stare at me through the front glass. When I still don’t take the hint, the female paces back and forth at the front, looking her brightest and most conspicuous, as though trying to attract my attention, while the male reverts to his drab everyday attire and dejectedly resumes his futile vigil at the feeding station. If not for their well-rounded cross-sections, one would think they were dying of hunger, making it difficult to resist their puppy-dog antics. Just sitting there ignoring them makes me feel like a first-class heel. Sheesh–talk about your guilt trips…Dang! I hate fast days." (Giwojna, Jun. 2002)

    There you have it, mom — everything you need to know about feeding Ocean Rider seahorses. If you follow these feeding tips, it should help keep your next seahorses eating their best and you will soon find that keeping them well fed is fun and easy. Feeding time for my seahorses is always a high point in my day. They do appear amazingly like fire-breathing Dragons when they eat frozen Mysis — it looks for all the world like smoke is shooting out of their "ears" when they eat enriched Mysis, due to the pulverized particles they expel from their gills after slurping it up (Gilchrist, 2002).

    So take a moment to enjoy the show when feeding your seahorses. Make sure they’re all eating well, and use this opportunity to look them over closely for wounds, injuries, or signs of disease. Seahorses are natural-born gluttons. Ordinarily, these galloping gourmets are ALWAYS hungry, so when a seahorse is off its feed, that’s often an excellent early indicator that something’s wrong. It Early detection of a potential problem can be the key to curing it, so it’s a good idea for the alert aquarist to observe his prize ponies while they put on the ol’ feed bag. Make sure they all show up for mess call, are acting normally, and have a well-rounded abdomen when they’re done eating.

    Before I sign off, I would also like to emphasize one more point regarding feeding frozen foods. Whether it is a tank with lots of live rock, a modified minireef, a seagrass system or a mangrove biotype, a well-designed seahorse setup is an elaborate environment. A certain level of complexity is necessary in order to assure that our seahorses behave naturally (Topps, 1999) and to provide our ponies with plenty of hitching posts and shelter, and enough sight barriers to assure them a little privacy when they feel the need to be alone. Their homemade habitat may thus take the form of a labyrinth of live rock, an intricate arrangement of corals and gorgonians, a well-planted bed of seagrass or macroalgae, or a full-fledged reef face. When feeding seahorses in such intricate surroundings, the worst thing you can do is to scatter a handful of frozen Mysis throughout the tank to be dispersed by the currents and hope that the hungry horses can track it all down. Inevitably some of the frozen food will be swept away and lodge in isolated nooks and crannies where the seahorses cannot get it. There it will begin to decompose and impair your water quality, which is why ammonia spikes are common after a heavy feeding. Or it may be wafted out into the open again later on and eaten after it has gone bad. Either outcome can lead to dire problems. Target feeding the seahorses or training them to use a feeding station are the best ways to avoid such complications.

    Best of luck with your new arrivals, mom!

    Dear mom:

    Sure, it’s not a bad idea at all to perform a partial water change on a small 20-gallon aquarium in some of the polluted shipping water found its way into the tank.

    It is standard operating procedure to leave seahorses in the aquarium while you are making partial water changes. It is less stressful for the seahorses to stay put that it is to handle them and temporarily relocate them while you are performing maintenance on the aquarium.

    When you are siphoning out the water that will be replaced during a water change, most hobbyists find it beneficial to vacuum a portion of the substrate as they do so. This is helpful for removing fecal pellets and reducing the amount of detritus in the substrate, as well as removing any food that may begin to degrade and degrade your water quality. Often they will vacuum a different portion of the substrate each time they perform a water change, so that after several water changes, most all of the substrate has been vacuumed lightly at least once during that time. If you find the siphoning stirs up to much sediment or releases too much detritus, then you can use dip tubes for removing fecal pellets, uneaten food, etc., from the aquarium in lieu of a thorough vacuuming.

    It’s normal for some detritus and sediment to be stirred up during a water change, or when siphoning over the bottom or vacuuming the substrate, but normally the mechanical filtration in the does a good job of filtering out the suspended particles within a matter of a few hours. If not, you can hook up a diatom filter on the aquarium and run it for an hour or so to remove suspended particles and polish the water. As long as you change the mechanical filtration media regularly to remove the sediment and detritus it has collected, this is generally beneficial for the aquarium.

    Here are some additional water changing tips to keep in mind when making a partial water change, mom:

    If the tap water or well water in your town is of dubious quality, and you don’t mind lugging containers of water home from the pet store, then purchasing pre-mixed saltwater from your local fish store is often a good option. Many seahorse keepers purchase reverse osmosis/deinonized water (RO/DI) for their water changes. Most well-stocked pet shops that handle marine fish sell RO/DI water as a service for their customers for between 25 and 50 cents a gallon. For example, WalMart sell RO/DI water by the gallon for around 60 cents.

    Natural seawater is another good option for a seahorse setup. Like RO/DI water, natural seawater can often be purchased at fish stores for around $1.00 a gallon, depending on where you live. It sounds expensive, but when you consider the alternative — paying for artificial salt mix and RO/DI water and mixing your own saltwater — then natural seawater is not a bad bargain at all. It has unsurpassed water quality and seahorses thrive in it.

    Personally, I really like the convenience of mixing up a relatively large quantity of saltwater in a plastic garbage can, rather than mixing it by the bucket full on a weekly basis. Using a clean 30-40 gallon capacity plastic garbage can allows me to mix up enough saltwater for a whole month’s worth of weekly water changes at one time. Which assures that the freshly mixed saltwater will be well aged and thoroughly aerated, and that any chlorine or residual ammonia will have at plenty of time to have dissipated before it’s used. And it also allows you to preadjust the saltwater to match the exact conditions in your aquarium very accurately. It’s always a good idea to keep some premixed saltwater on hand in case of an emergency, when a quick water change becomes necessary. Here are some more suggestions for mixing your own saltwater and making regular partial water changes in your seahorse setup, com:

    Water Changing Tips

    If you find that performing a major water change seems to cause your seahorses distress, try adjusting your water changing schedule so that you are performing smaller water changes more frequently rather than larger water changes less often. For instance, if you have been performing 25%-50% water changes monthly, switch to administering a 10% water changes every week or try making 5% water changes biweekly instead. You’ll find the smaller water changes are much less stressful on the aquarium inhabitants.

    Be sure to observe all of the usual water changing precautions as well. For example, it’s an excellent idea to use Reverse Osmosis (RO) or Deionized (DI) or RO/DI water for your changes because it’s much more pure than tap water. However, water purified by such methods is very soft and must be buffered before it’s used so it won’t drop the pH in your aquarium when it’s added.

    When mixing saltwater for your marine aquarium, it’s important to fill your container with all the water you will need BEFORE adding the salt mix. In other words, if you are mixing up 5 gallons of new saltwater, fill the mixing containing with 5 gallons of water and then add the salt. If you do it the other way around — dump the salt mix in the container and then start filling it with water, the water can become saturated with salt to the point that the calcium precipitates out. This calcium precipitation will turn the water milky and can also lower the pH to dangerous levels.

    Water changes can also sometimes be a problem because of the supersaturation of gases in tap water. Tap water distribution systems are maintained under pressure at all times, both to insure adequate flow and to prevent polluted water from outside the pipes from entering in at leaks. Any additional gas introduced into these pipes (from a leaky manifold, for example) will be dissolved at these higher partial pressures, and will often be supersaturated when it emerges from the tap. Also, gases are more soluble in cold water than warm, so when gas-saturated cold water emerges from the tap and warms up in an aquarium, or is warmed up and preadjusted to aquarium temps prior to making a water change, the water can become supersaturated. This must be avoided at all costs because gas supersaturation is one of the contributing factors that can cause Gas Bubble Disease in seahorses and other fish. To prevent this, tap water should be allowed to sit for several days beforehand or gentle aeration can be used to remove gas supersaturation before a water change (just make sure your airstones are not be submerged greater than 18 inches while you’re aerating your freshly mixed water).

    There are a few accessories you should keep on hand to make water changing easier: one or more large capacity plastic garbage cans or Rubbermaid vats for mixing up new saltwater; a small powerhead for stirring and circulating the water while it mixes; a submersible heater to adjust the temperature of the newly mixed water; a large diameter siphon hose; a couple of new plastic buckets that hold 3-5 gallons.

    First use a clean plastic bucket to fill up the garbage can with 10, 20 or 30 gallons of water or however much you want to mix up at one time. Add the proper amount of artificial salt mix for that much water, and toss your small, cheap powerhead into the garbage can to stir it up. While it’s mixing, put the submersible heater in to adjust the water temp, and add dechlorinator or detox if using tap water (if using reverse osmosis deionized water, or another softened source, be sure to add a pH buffer to the new water). Let the new batch of water mix, aerate, and stabilize for 24-48 hours before you perform the water change and check to make sure the temperature and pH of the new water matches your aquarium. Some artificial salt mixes produce residual amounts of ammonia when newly mixed; aerating the freshly mixed saltwater for 24-48 hours will dissipate and remaining traces of chlorine or ammonia.

    If you follow the steps outlined above when mixing up new saltwater prior to performing a water change, the water cannot become saturated with salts, the calcium will not precipitate out, the newly mixed saltwater will be crystal clear and the water exchange should go smoothly.

    Best wishes with all your fishes, mom! Good luck working out a water changing regimen that is ideal for your needs and schedule, as well as the needs of your seahorses.

    🙁 I do not think my guys are going to make it – the female was laying on the sand and male breathing kinda fast – I moved them to the 55 – but it is not really fully cycled – however they have perked up some-

    🙁 if they do not make it I will give up on horses for now and stick with just salt water fish….

    Dear mom:

    Yikes — that doesn’t sound good at all! What happened? It sounded like your new seahorses were settling in nicely and the female in particular was thriving. Did you perform the partial water change we discussed yesterday?

    I am thinking that your 20-gallon aquarium may have experienced a serious ammonia and/or nitrite spike, which has knocked your seahorses for a loop. Respiratory distress, rapid breathing, and laying on the bottom are some of the symptoms of ammonia poisoning and nitrite toxicity. If so, making an emergency transfer to your 55-gallon aquarium was an excellent idea, since that removed the seahorses from the toxic environment in the 20-gallon tank, and the larger water volume in the 55-gallon aquarium will be much more resistant to spikes in the ammonia and nitrite levels even if it has completely cycled.

    If you can provide me with the current readings for the following aquarium parameters in your 20-gallon seahorse tank and the 55-gallon tank, then we can confirm whether or not an ammonia and/or nitrite spike is causing this problem and proceed accordingly. I need to know the current levels of ammonia, nitrite, and nitrate in both aquariums as well as the water temperature, specific gravity, and pH.

    The most obvious symptoms of ammonia poisoning and nitrite toxicity are a loss of equilibrium, hyperexcitability, increased respiration and oxygen uptake, and increased heart rate. At extreme ammonia/nitrite levels, fish may experience convulsions, coma, and death. Seahorses exposed to less extreme ammonia/nitrite levels will struggle to breathe. They will be lethargic and exhibit rapid respiration. They may appear disoriented, periodically detaching from their hitching posts only to sink to the bottom.

    Ammonia poisoning and nitrite toxicity are completely reversible providing the seahorses weren’t exposed to toxic levels for too long, and the best first aid you can provide for ammonia/nitrite poisoning is to immediately transfer the seahorses into clean, well-aerated saltwater with zero ammonia and zero nitrite. It sounds like you already accomplished that, mom, so that was a wise decision and should help.

    The next thing you should do is to give the seahorses a quick 10-second dip in concentrated methylene blue to help them recover, as discussed below.

    Exposure to moderate levels of ammonia and nitrite, or high levels of nitrates, can change the normal hemoglobin in the seahorse’s blood stream to a form (i.e., methhemoglobin) that is no longer able to transport oxygen. If this becomes severe enough, it will leave the affected seahorse starved for oxygen, which makes it very weak and fatigued. As a result, the affected seahorses may detach themselves from their hitching posts periodically and rest on the bottom, unable to exert themselves in their weakened condition. As you can imagine, being deprived of oxygen really wipes them out in terms of loss of energy and stamina. And it also results in respiratory distress, and rapid, labored breathing as they try to oxygenate themselves and compensate for the lack of normal hemoglobin.

    One of the properties of methylene blue is that it can reverse this process and convert the methhemoglobin in the red blood cells back into normal hemoglobin, which can then pick up and transport oxygen again as usual. That’s why it is so helpful in relieving shipping stress and treating ammonia exposure and nitrite poisoning. For this reason, you may want to pick up some methylene blue at your local fish store and keep it on hand in case it is ever needed (the Kordon brand of methylene blue is best, in my opinion). So be prepared to give the seahorses a quick dip in methylene blue as soon as possible.

    The usual criteria for determining whether or not methylene blue is needed to help seahorses recover from exposure to high levels of ammonia is their respiration. If the seahorse has labored breathing — huffing or rapid respiration — then methylene blue is called for. Likewise, if the seahorse is experiencing convulsions or it’s behavior otherwise indicates it is suffering from more than temporary disorientation and loss of equilibrium, such as lying prostrate on the bottom, unable to right itself again at all after two or three hours have passed, it may benefit from methylene blue to assist its recovery.

    Commonly known as "meth blue" or simply "blue," methylene blue is a wonderful medication for reversing the toxic effects of ammonia and nitrite poisoning. Methylene blue transports oxygen and aids breathing. It facilitates oxygen transport, helping fish breathe more easily by converting methemoglobin to hemoglobin — the normal oxygen carrying component of fish blood, thus allowing more oxygen to be carried through the bloodstream. This makes it very useful for treating gill infections, low oxygen levels, or anytime your seahorses are breathing rapidly and experiencing respiratory distress. It is the drug of choice for treating hypoxic emergencies of any kind with your fish. However, methylene blue will destroy nitrifying bacteria so it should be used in a hospital tank or as a brief bath or dip only (if used in an established aquarium, it will impair the biological filtration and the tank may need to be cycled all over again).

    Here is some more information that may be helpful when you treat the seahorses with methylene blue, mom:

    If you can obtain the Kordon brand of Methylene Blue (available at most well-stocked local fish stores), there are instructions for administering it as a very brief, concentrated dip are as follows:

    For use as a dip for treatment of fungus or external parasitic protozoans and cyanide poisoning:
    (a) Prepare a nonmetallic container of sufficient size to contain the fish to be treated by adding water similar to the original aquarium.
    (b) Add 5 teaspoons (24.65 ml) per 3 gallons of water. This produces a concentration of 50 ppm. It is not recommended that the concentration be increased beyond 50 ppm.
    (c) Place fishes to be treated in this solution for no longer than 10 seconds.
    (d) Return fish to original aquarium.

    When you administer such a dip, hold the seahorse in your hand throughout the procedure and time it closely so that the dip does not exceed 10 seconds.

    And here are Kordon’s instructions for administering the methylene blue in a hospital tank if longer-term treatment seems appropriate to reverse more severe cases of nitrite poisoning and ammonia toxicity:

    As an aid in reversal of nitrite (NO2-) or cyanide (CN-) poisoning of marine and freshwater aquarium fishes:
    (a) Remove carbon filter and continue to operate with mechanical filter media throughout the treatment period.
    (b) Add 1 teaspoon of 2.303% Methylene Blue per 10 gallons of water. This produces a concentration of 3 ppm. Continue the treatment for 3 to 5 days.
    (c) Make a water change as noted and replace the filter carbon at the conclusion of the treatment.

    See the following link for more information on treating with Kordon’s Methylene Blue:

    If you obtained a brand of methylene blue other than Kordon, just follow the instructions the medication comes with.

    One other tip, mom: if you ever need to handle seahorses to administer first aid measures or treat them in a hospital tank, it’s best not to net them when you are manipulating the seahorse:

    Handling Seahorses

    I do not like to use an aquarium net to transfer or manipulate seahorses, since their delicate fins and snouts can become entangled in the netting all too easily. I much prefer to transfer the seahorses by hand. Simply wet your hand and fingers (to avoid removing any of the seahorse’s protective slime coat) and scoop the seahorses in your hand. Allow them to curl their tail around your fingers and carefully cup their bodies in your hand to support them while you lift them out of the water. When you gently immerse your hand in the destination tank, the seahorse will release its grip and swim away as though nothing out of the ordinary has happened.

    Composed of solid muscle and endowed with extraordinary skeletal support, the prehensile tail is amazingly strong. Indeed, large specimens have a grip like an anaconda, and when a 12-inch ingens or abdominalis wraps its tail around your hand and tightens its hold, its vise-like grip is powerful enough to leave you counting your fingers afterwards!

    In fact, it can be quite difficult to remove an attached seahorse from its holdfast without injuring it in the process. Never attempt to forcibly detach a seahorse from its hitching post! When it feels threatened, it’s instinct is to clamp down and hold on all the tighter. When you must dislodge a seahorse from its resting place for any reason, it’s best to use the tickle technique instead. Gently tickling the underside of the tail where it’s wrapped around the object will usually induce the seahorse to release its grip (Abbott, 2003). They don’t seem to like that at all, and will quickly let go to move away to another spot. Once they are swimming, they are easy to handle.

    Best of luck treating the seahorses with methylene blue to help them recover from this problem, mom.

    Respectfully,
    Pete Giwojna

    The ammonia was .5-1 in the 20 gallon and is .25 in the larger – I have used a product called stability – and prime –
    the ph seems low 7.5 – what can I do to get it up? was about the same in both tanks

    the nitrite was good –

    the horses seem happier in the 55 gallon – I assume that they will be fine in a 55 alone ( except for shrimp and gobies….)

    Dear mom:

    Thanks for getting back to me promptly. Your readings indicate that an ammonia spike has occurred and that is what is ailing your new seahorses.

    Any ammonia level above 0.05 mg/L or ppm is a cause for concern and can be harmful to fish and invertebrates, and the ammonia level in your 20-gallon aquarium (0.5-1.0 ppm) is 10 to 20 times higher than the acceptable level. Ammonia spikes such as this are such a common problem for newly established aquariums that when fish become ill as a result it is commonly known in the aquarium trade as "new tank syndrome."

    In other words, your seahorses are indeed suffering from ammonia poisoning, mom, and your quick thinking in transferring them into the 55-gallon aquarium probably saved their lives. The ammonia level in the 55 gallon tank isn’t great — 0.25 ppm is still 5 times the acceptable level of ammonia at which harmful effects begin to occur, but that’s a heck of a lot better than the conditions in the small 20-gallon setup, and the 55 gallon tank will be more resistant to high ammonia spikes because of its large water volume.

    Be sure to pick up some methylene blue from your local fish store as we discussed in my previous post, since it is probably going to be needed before this crisis is over. As you know, it can reverse the effects of ammonia poisoning and nitrite toxicity if the affected fish are not too far gone.

    The other thing you need to do as soon as possible is to go to a well-stocked fish store and obtain some marine Bio-Spira and add it to your aquarium according to instructions. Bio-Spira is a product offered by Marineland which contains the live bacteria necessary to convert ammonia and nitrite into harmless nitrate. It is available for both freshwater and marine aquariums, so of course be sure to get the Bio-Spira for saltwater. Call around until you find a fish store in your area that has it available. Just use it as explained below and it should help get the ammonia level in your 55 gallon aquarium back down to where you want it:

    IMPORTANT:
    BIO-Spira is a "live" bacteria culture that is sold refrigerated and must be kept refrigerated until used. It can not be overdosed. Repeated dosing of your aquarium with ammonia removing liquids (such as BIO-Safe, Amquel, Ammo-lock and Aqua-Safe) can inhibit the beneficial action of BIO-Spira. Ammonia removing liquids should only be used to initially treat tap water. It is normal to have a small amount of ammonia or nitrate during the first few days after set-up. These concentrations are not harmful and will quickly drop to zero with proper use of BIO-Spira.

    DIRECTIONS FOR USE:
    Shake well before each use. Use 1 ounce (29.6 ml) of BIO-Spira per 30 gallons of water. BIO-Spira cannot be overdosed. Keep refrigerated. Be sure to shut off any UV sterilizers and remove medication by means of a water change or activated carbon.

    Be sure to get the marine BioSpira for saltwater aquariums, mom. If you can obtain some precured live rock from your local fish store and add it to the 55 gallon aquarium that will also help by providing additional biological filtration ability to the tank.

    With regard to the pH, it can be raised in by obtaining one of the commercially made products designed to adjust the pH upwards in saltwater aquariums and using it according to the instructions. Such a product should be available from any good LFS that handles marine fishes and invertebrates; they typically include sodium bicarbonate as their primary active ingredient and are often marketed under names such as "pH Up" or something similar. If you wish, ordinary baking soda (bicarbonate) from your kitchen will work just as well for elevating the pH.

    However, mom, in your case I wouldn’t attempt to raise the pH right now since the relatively low pH is helping to protect the seahorses from the harmful effects of the ammonia. Remember, ammonia is less toxic at low pH and becomes much more toxic at higher pH. This is because ammonia exists in water in an equilibrium between two different forms — a nontoxic ionized form usually referred to as ammonium (NH4+) and an un-ionized form (NH3), which is highly toxic. Ammonium (NH4+) is completely harmless to fishes since the ionized ammonia molecule cannot cross the cell membrane and enter their cells. Note that only difference between harmless NH4+ and deadly NH3 is the addition of a hydrogen ion (H+), which converts toxic ammonia to nontoxic ammonium. At low pH, the extra hydrogen ions (H+) of acidic water are readily available to attach to the ammonia molecule, converting most of the ammonia to ammonium: NH3 + H+ —> NH4+. But at high pH, under alkaline conditions, exactly the opposite occurs. At high pH, the abundance of hydroxide ions (OH-) in alkaline water strips the extra hydrogen ion (H+) away from ammonium, rapidly converting most of it to deadly ammonia: OH- + NH4+ —> NH3 + H20. In other words, the higher (more alkaline) the pH, the more ammonia is present in the dangerous un-ionized form (NH3), which easily crosses cell membranes and enters the body.

    In short, mom, adjusting the pH upwards at this time would only make the ammonia more toxic to the seahorses. Wait until you get the ammonia problem under control before you worry about gradually adjusting the aquarium pH.

    Best of luck weathering this crisis and getting your aquarium’s back on track, mom. Be sure to go to your local fish store as soon as feasible to obtain some methylene blue, marine BioSpira, and hopefully some precured live rock. The BioSpira and live rock can go in your 55-gallon aquarium immediately, but if it becomes necessary to use the methylene blue, it should only be used as a dip or in a hospital tank, as we discussed in my previous post.

    Respectfully,
    Pete Giwojna

    Max and Ruby have perked up – Ruby will eat out of my hand – Max backs off and wont take from me – but will eat on his own.

    Dear mom:

    Thanks for the update! It’s a relief to hear that your new seahorses are doing much better now and eating well. Continue to be patient with Max and you’ll soon have him eating right out of your hand as well. Males are often more shy and retiring than the females, and need a bit more coaxing before they trust their keepers enough to be hand fed, but he should learn fast by following Ruby’s example.

    Be sure to keep a close eye on the ammonia and nitrite levels in the new 55-gallon aquarium. Once the aquarium completes the cycling process with the aid of the BioSpira, and the ammonia and nitrite levels are back down to zero again, the seahorses should be out of the woods. Until that time, be sure to keep some methylene blue on hand in your fish room in case it’s needed to help counteract the effects of a spike in the ammonia or nitrate levels.

    Best of luck with your new seahorses, mom!

    Respectfully,
    Pete Giwojna

    Once I know that Max and Ruby are good can I add a pair of sunburst? do they mix with the mustangs?
