Abstract: One of the aims of aquaculture is the increase of productivity of aquatic resources through deliberated manipulation of its processes. The nutrition of organisms is the highlight aspect in aquaculture, that is why the effect of different diets (live food enriched with heterotrophic bacteria and Biofloc) in A. ocellatus and D. rerio were evaluated in this investigation. The organisms of each specie were divided in six plastic containers of 80L, and every 15 days, total population weight of each specie was taken to obtain absolute growth rate (AGR) and instantaneous growth rate (IGR) values. In general, the highest gain of weight in both species was obtained with the diet of live food enriched with bacteria produced in a Biofloc system, with an AGR of 0.037g and an IGR of 2.023g in D. rerio culture, and an AGR of 0.089g and IGR of 2.702g in A. ocellatus culture. It was concluded that this type of diets is a better option than commercial food, which is the normal food that was applied to in ornamental fish, pointing out that live food enriched with bacteria diet produced in a Biofloc system, obtained better results than only Biofloc diet.
