The main objective of this study was to evaluate the effect of three foods on the growth and survival of juveniles of arahuana Osteoglossum bicirrhosum. 81 specimens (6.5 ± 0.36 cm and 1.03 ± 0.03 g) were used and distributed in aquariums with 15 L of water at a density of 0.6 fish L-1. Three foods were used: commercial feed, chironomids Chironomus sp. and live specimens of Poecilia reticulata, with three replicas distributed in a completely randomized design (CRD) for 30 days. The results show that fish fed with chironomids and balanced feed obtained a significant performance (p <0.05) in weight, specific growth rate, relative growth rate and condition factor compared to juveniles fed live fish. However, no significant differences (p> 0.05) in total length and survival were found in the different feeding treatments. In conclusion, the use of chironomids and balanced food show a better performance in weight growth and condition factor in juveniles of arahuana O. bicirrhosum.
