How to Feed Fish Frozen Food

Frozen food is a good alternative to fresh fish food. It often is high in protein and comes in many varieties, including brine shrimp, which is beneficial for fish that are getting ready to breed, and mysis, a high-protein shrimp ideal for corals kept in a reef tank. Tubifex worms are a favorite of many fish. Daphina, cockles and mussels and bloodworms are other frozen varieties. Be sure to thaw food out properly before dropping it in a tank, as fish have sensitive intestinal linings that may not tolerate and process food with low temperatures.

Instructions

    • 1

      Remove the food from your freezer and decide how much to use based on the type, size and weight of the fish. Place the selected amount of food on a plastic dish and allow it to thaw, but for no more than 30 minutes to prevent spoilage.

      Add extra nutrients to the food by combining it with a liquid multivitamin, many types of which are available from pet stores. Pour the liquid over the food during the final minutes of thawing.

      Check the consistency of the food five minutes after applying the multivitamin. If the consistency is soft and spongy, then the food is fully thawed and ready for you to feed it to your fish. Take a small piece of the food and put it just underneath the water surface. Gently squeeze the food between your fingers so that it drops away in small pieces, allowing the fish to swim up and collect it.

      Watch what happens immediately after dropping the food in. Use tongs to feed the fish individually if it becomes clear that some are not getting enough because a dominant fish is hogging it.
