The protein and lipid requirement for the growth of juvenile clownfish, Amphiprion ocellaris, was evaluated under laboratory conditions. Two experiments were conducted. In the first experiment (E1), eight diets with four different protein levels (370, 410, 440, and 460 g/kg) and two lipid levels (80 and 100 g/kg) were evaluated during 105 days with 10 clownfish (considering each individual as a replicate). In the second experiment (E2), three isoproteic diets (430 g/kg) with three lipid levels (100, 110, and 120 g/kg) and 10 pairs of clownfish (considering a pair as a replicate) were evaluated for 100 days. A commercial diet was used as the control. The efficiency of the diets was evaluated in relation to the survival and growth. The average survival of fish during E1 was 100% and during E2 was 97%. Through E1, the weight gain (mg) obtained with the control diet and the diets with high protein content were similar, while the diets with protein/lipid ratios of 370/80, 370/100, and 410/80 exhibited significantly lower results. In contrast, during E2, the control and 430/100 diets promoted greater weight gain. Based on these results, it is possible to conclude that the requirement of protein/lipids for juvenile clownfish is 430/100.
