Marine Fish Nutrition (page 3) After exploring some of the
factors involved in proper fish nutrition, what can be done to ensure that the fish are receiving the proper amounts of
protein, carbohydrates, lipids and vitamins? The first and most logical solution is to feed them their natural foods.
For many of us this is not practical, however, with the increased popularity of "live rock" in marine aquariums many of
the smaller, crustaceans eating fish species can be provided with a renewable live food source. The "live rock" brings
with it many microscopic crustaceans that many fish relish.
If the tank it setup without fish for a few months, these animals are given the chance to multiply to such an extent that when a few fish are added, the food animals can reproduce at a pace to keep up with the rate of predation. Of course, this is a delicate balance and the sudden addition of too many fish can cause irreversible damage. For herbivorous fish, live plants such as the macroalgae (i.e. Caulerpa) can provide a natural food source. In the case of other fish, such as butterflyfish and large angelfish species, the situation is trickier due to some species dietary requirements that we cannot possibly duplicate in the aquarium. For the others a diet in a rich variety of dried and frozen foods and adding vitamin supplements to the food before being given to the fish. One excellent method is the use of a homemade food preparation, to which you can add vitamin supplements; by soaking freeze-dried brine shrimp, Tubifex and Hakari Turbellina in a small container of the solution before feeding it to the fish. |
