I am confused on the addition of the vibrance2 to the frozen mysis shrimp. Right now i take a frozen cube and add a little of the tank water to it and then after it thaws dump it in the tank and the seahorses eat. my question is how to add the vibrance2 to the frozen shrimp. also, should i be feeding more than 1 cube 2 times a day. i have 7 seahorses, 3 from a local pet shop and 4 from ocean rider. the ocean rider horses are alot more active than the others but all seem to be eatingNovember 10, 2006 at 12:06 am #3028Pete GiwojnaGuest
There are probably as many different techniques for enriching frozen Mysis with Vibrance as there are seahorse keepers, and they are all perfectly acceptable as long as they end up with fortified shrimp in the seahorses’ bellies. But here are some suggestions that described the best methods for the enrichment step that I and other hobbyists prefer, which should give you a better idea how to proceed:
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 clouding of the 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 (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.
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, captive-bread-and-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.
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 relicta 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.
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 — 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.
The recommended feeding regimen above is based on the jumbo Mysis relicta from Piscine Energetics (PE) in Canada, and it’s difficult to translate that into the feeding cubes you have been using. (I agree with plenty that the PE frozen Mysis relicta is a much better product.)
If you want to upgrade to the superior PE Mysis relicta with better nutritional content, you can order it online from Premium Aquatics (see link below). The Piscine Energetics frozen Mysis relicta is now available graded for size. You can get the usual jumbo Mysis relicta or smaller Mysis depending on whatever side shrimp your seahorses are accustomed to eating now:
