The aim of this study was to evaluate different feeding strategies in the species Hypancistrus
sp. (14.22 ± 6.19g and 7.436 ± 0.863 cm) in the laboratory. 5 fishes/aquarium aquariums (60
cm long x 45 cm high x 40 cm wide) were distributed in 15 experimental units with a useful
volume of 76 L each, in a recirculation system in the laboratory) and TPC (pasty ration + feed
with the purpose of accentuating the color of the fish) during a period of 80 days. For specific
growth rate, the acaris from the TP, TPC and TA treatments (p<0.05) had better performance.
The fishes from the TC and TA treatments showed a better correlation between weight and
length, and also the relative condition factor indicated well -being of the fishes submitted to
different diets. The other zootechnical parameters evaluated did not differ significantly for the
fish of the different treatments (p>0.05). A natural reproduction was registered for acaris fed
with the specific ration for coloration. It is concluded based on the results that the most suitable
for the species Hypancistrus sp. it is fed with a dry diet (garlic base) associated with a wet diet
(pasty ration).
