    Hi all,

    I have just purchased a pair of Reidi and I am wondering how much food I am supposed to give them each day. They were captive bred and raised on frozen food.

    I was sold Mysis Shrimp (bio encapsulated with vitamins) and Spirulina Brine Shrimp (bio encapsulated with vitamins) both made by a company called Hikari Sales USA Inc.

    Both seahorses are feeding well, but I am worried about over/under feeding.

    I am at home all day so I can do many feeds a day.

    Thanks
    Leonie

    Dear Leonie:

    Congratulations on your new Brazilian seahorses (Hippocampus reidi)! Many hobbyists consider the brightly colored yellow or orange color morphs of H. reidi to be the most beautiful of all the seahorses, but they can sometimes be finicky eaters. It’s good to hear that your new H. reidi have good appetites and are eating well.

    It’s okay to use the Hikari frozen brine shrimp to supplement their diet from time to time, as long as the H. reidi accept it readily, but even enriched frozen brine shrimp is not adequate for the long-term diet of any seahorses. The Hikari frozen Mysis should serve as your seahorses staple, everyday diet, and you can offer them the frozen brine shrimp now and then for a little more variety.

    There is no simple answer to the question, "How many frozen Mysis should each of my seahorses be eating per day?" That depends on the size of the frozen Mysis, which varies considerably from brand to brand, the size of the seahorses themselves, and the size of their appetites, which is also quite variable from one pony to another, and a number of other factors. Mustangs and Sunbursts (Hippocampus erectus) of average size usually eat between 2-7 of the big Piscine Energetics Mysis relicta per feeding, but rather than trying to keep track of how many frozen Mysis each of your seahorses has eaten, it’s a better idea to check them for well-rounded abdomens after they have eaten a big meal and to observe their fecal production in order to make sure they are all getting enough to eat on a daily basis, as discussed below.

    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 or three 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 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 after a good feeding, the cross-section of their abdomens should appear convex "( )" or flush "l l" rather than concave ") (" or pinched in.

    Before I go any further, I would first 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.

    Target Feeding Frozen Mysis

    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 and stare it down forever 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.

    Feeding Stations

    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.

    For example, one of the artificial Velvet Stone Corals offered by Living Color (<http://www.livingcolor.com/coral.cfm&gt;), in particular, makes an absolutely superb natural-looking feeding station for seahorses! The inner whorls of the colorful coral form a deep bowl to contain the frozen Mysis and protect it from being swept away by water currents, whereas the outer whorls provide convenient places for several seahorses to perch while they wait to eat:

    Item number 360 DPK Velvet Stone Coral (Montipora sp.) from Living Color (11"L x 8"W x 7.5"H)

    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:

    <<http://www.wetwebmedia.com/ca/volume_2/cav2i5/seahorse_feeders/seahorse_feeders.htm>&gt;

    For best results, I recommend elevating the feeding station, which provides several benefits for our galloping gourmets:

    (1) First and foremost, it isolates the feeding trough from the bacteria-laden substrate and provides the seahorses with a sanitary lunch counter from which to feed.

    (2) Secondly, it keeps the feeding station beyond the reach of bottom scavengers such as bristleworms, Nassarius snails and hermit crabs, which are attracted to the frozen Mysis.

    (3) Finally, it provides a sterile feeding surface for the ponies that is easy to remove and keep clean, thereby making it a breeze to dispose of leftovers, which safeguards your water quality. Keeping the feeding tray elevated makes it convenient to clean and sterilize between feedings.

    Some creative hobbyists elevate their feeding stations by attaching an upturned seashell or an improvised feeding tray to a strong aquarium magnet. This allows them to move the feeding station to any location within the tank quickly and easily, and to adjust its height as desired without ever putting their hands in the aquarium. How nifty is that? And you thought those magnetic glass cleaners were only useful for cleaning algae from the aquarium glass…

    You can also buy ready-made feeding stations if you feel that would be easier than improvising one of your own. For example, the Aquarium Fish Dish sold here works well in some seahorse tanks, if you don’t mind adding that particular piece of apparatus to your tank:

    <http://www.thatpetplace.com/pet/group/10853/product.web&gt;

    And don’t forget to check out the ultra-cool feeding station shown in the picture at the link below, which was fashioned from a seashell by a very clever seahorse keeper. Notice how the hobbyist inverted a Lambis shell or scorpion seashell and then used a Dremel tool to cut away part of the main body whorl, creating a perfect feeding trough. As you can see, the fingerlike projections that extend from the aperture of the Lambis shell (and all other scorpion shells) make handy hitching posts for a hungry Hippocampus. This enterprising aquarist has also attached a convenient suction cup for elevating and mounting his fancy feeding station to the wall of the tank. Outstanding! So be creative when you’re setting up a feeding station and you can come up with a design that looks great and is also very functional:

    http://www.greenighs.com/seahorses/tank/first_snick.jpg

    However you go about it, and whatever sort of feeding dish or trough you fancy for your seahorse tank, setting up a feeding station is a convenient, sanitary method of feeding seahorses that works very well for most home hobbyists.

    Avoid Overfeeding & Fast Seahorses Once a Week

    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)

    Okay, Leonie — that’s the quick rundown on feeding your new Brazilians. 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 amiss in the aquarium.. 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. Target feeding makes it hard to miss when one these chow hounds is off its feed, tipping off the alert aquarist to a potential problem.

    Best of luck with your new Hippocampus reidi, Leonie!

    Happy Trails!
