Secondly, freezing foods lets them retain almost all of their nutritional value. Finally the frozen varieties of both herbivorous and carnivorous fish foods offer an excellent supplemental source to any fish diet.
Most of the frozen foods are specially grown in conditions that give them the highest nutritional content available for your fish.

In addition to the special conditions that most of the frozen krill and other animals were raised in; there is the nutritional element of being natural food. These frozen foods are what the fish are designed to digest. Many types of flake and pellet foods can be difficult for the fish to digest because they are not natural sources of food.
Frozen fish foods have often been associated with an increased vibrancy of fish coloring. This is because the fish are better nourished when they have things like bloodworms and brine shrimp to eat. Their color increase is related to their intake of certain vitamins and minerals offered by these foods.
The freezing process does not destroy any nutrients and there is very little nutrient loss during frozen storage. This provides a great shelf life advantage in the bulk purchase of frozen foods for your fish. Unlike flake and pellet foods which carry a very short shelf life the frozen varieties do not contain the short shelf life. When specials on bloodworms or brine shrimp surface it is ok to take advantage of the deals, with no need to worry about the 30 day consumption.
