Frozen fish food is frozen food for ornamental fish. The nutritional components are predominantly of animal origin and are handled in frozen form. Different portions are common: blisters, bars or flat packs. Frozen food for the aquarium is defrosted before feeding and rinsed carefully. Make sure that it is not too cold when feeding. Also important: the cold chain must not be broken until thawing. In addition, you should not refreeze any thawed food. Frozen food for fish is a good alternative to live food and is much more convenient to stock. Common components of the frozen ready-made food for fish are microorganisms, larvae, small crustaceans, worms, crustacean eggs and small pieces of molluscs.
