How to Feed Marine Fish With Frozen Mysis

Frozen mysis shrimp are favored by numerous saltwater fish. They provide balanced nutrition, including high concentrations of fatty acids and proteins, making them an ideal staple and spawning food. Both saltwater and freshwater species of this shrimp exist, leading to followings among keepers of fish as diverse as seahorses and discus fish. Frozen mysis provides a more convenient alternative to live shrimp for predators willing to take frozen foods.

Instructions

    • 1

      If necessary, cut frozen mysis to size. Frozen mysis often comes in either flat frozen slabs or "blister packs" of frozen cubes. If there is more food per "serving" than your fish can eat in under 30 seconds, cut to size with a razor blade or knife.

      Fill a small plastic cup with water from the main aquarium. Add mysis and allow to thaw. Do not heat the water. Swirling with your wrist or stirring can speed up the thawing.

    • 3

      Pour off the excess aquarium water. Frozen foods are often frozen in water high in phosphates which can upset your water chemistry.

    • 4

      Dump the mysis into the fish tank. Make sure it takes your fish around 15 to 30 seconds to eat all of the food. If they can consume it more quickly, you are most likely underfeeding. If it takes longer than 30 seconds, you are likely feeding too much and the extra can rot and foul the water.

    • 5

      In some territorial or timid fish, it is necessary to apply the food directly to them. One option is to use a turkey baster. To feed this way, fill the baster with aquarium water and shrimp and spray directly at the fish.

      Administer food by skewering it on a feeding rod, as an alternative to Step 5. To do this, pierce the individual mysis with the rod and push into the tank. Make certain the shrimp are at least half an inch from the pointed tip of the feeding rod to avoid injuring the fish.
