Frozen Foods for Marine Fish

Raising carnivorous marine fish means that you will need to look into feeding them meat. Providing them with frozen food is a good way to conveniently give them the food they need. Frozen foods are available from most fish shops and pet stores. They can be chipped into smaller portions and then thawed in a cup of aquarium water before being tossed into the tank.

  1. Frozen Sea Foods

    • Carnivorous marine fish can eat the fish that are purchased at the seafood counter of the grocery store. Shrimp, clams and squid can all be rinsed and chopped into consumable portions for fish. Frozen seafood can also be grated into shavings and then thawed. Be sure to avoid oily fish like herring and tuna because they will create an oily film in the water. Also, remove any uneaten portions of food from the tank quickly to avoid dirtying the water.

    Mysid Shrimp

    • Mysid shrimp are a nutritious food for marine fish as they are high in protein and fat. According to Pet Education, they are a useful food for enticing difficult or picky eaters. One factor to keep in mind is that mysid shrimp are not high in carotenoid pigments, which provide fish with their bright coloration. A diet that is composed mainly of mysid shrimp can cause some fish to lose their coloration.

    Brine Shrimp/Krill

    • Brine shrimp and krill are small crustaceans that can be found in a frozen form at most pet stores. They are rich in carotenoid pigments, which will keep the marine fish looking bright and colorful, but they tend to be lower in nutritional value than other options. However, they can be soaked in a food additive which will provide the fish with additional vitamins.

    Daphnia

    • Daphnia, also known as water fleas, provide marine fish with much needed roughage for their digestive systems. Though they are far more nutritious live than frozen, they can be used to supplement the fish's diet and to ensure continued healthy digestion.

    Bloodworms

    • Bloodworms are readily accepted by all marine fish, and they are very high in protein. It is important to limit the amount of bloodworms that are provided to a tank, as they make a better treat than a staple food. Bloodworms can be used to provide a fish with some variety in its diet.
