Freeze Dried Fish Foods
Freeze-dried fish food consists of whole organisms or chunks, freeze-dried to kill parasites and preserve natural flavor & most nutrients almost indefinitely. Many aquarists prefer freeze-dried fish food to live or frozen fish food, which can be a hassle to keep and to feed. If your fish prefer their food to be wriggling, using a manual feeder with a prong and wiggling dried food around tends to work just fine.
Freeze-dried fish food is generally not sufficient as a staple diet, but is essential to the well-rounded diet of carnivores, so regular supplementation is important.
