Resumen : With the study aimed to evaluate the effect of salinity and feeding frequency on growth, uniformity and survival of the angelfish Pterophyllum scalare and banded cichlid post-larvae. Were conducted two experiments in a completely randomized in a factorial 5 x 2, with five different sodium chloride concentrations (0; 2; 4; 6 and 8 g L-1) and two feed frequency (2 and 4 times per day). It was observed the water salinity and feeding frequency influenced significantly (p < 0,05) in torso length and body height in the angelfish larviculture. The eye diameter, was affected (p < 0,05) only by salinity, while the final standard length, standard length gain, head length, torso length, post-anal length, head height, body height, final weight, weight gain, specific growth rate and allometric condition factor differed significantly (p < 0,05) only for the feeding frequency. In the banded cichlid larviculture, there was a significant difference (p < 0,05) in the head length, post-anal length, head height and allometric condition factor by salinity and feeding frequency. The water salinity influenced significantly (p < 0,05) the final standard length, standard length gain, torso length, eye diameter, body height, survival hate and uniformity in weight. The feeding frequency influenced significantly (p < 0,05) the final weight, weight gain and specific growth rate. It was concluded that angelfish post-larvae can be grown with salinity up to 4 g L-1 without problems for the development and survival. On the other hand, the banded cichlid post-larvae had better survival hate in water without salt add. The feeding frequency of four times a day with artemia nauplii is the most recommended for the both species.
