Resumo: | Simpsonichthys boitonei Carvalho, 1959 has an evident sexual dimorphism, easily observed in the color pattern and body proportions. In order to know the differences in the diet between males and females, the stomach contents of 28 individuals was examined. The Sorensen's index of similarity showed 90.9% of food items in common between sex. The main food in this species is Cladocera as evidenced in terms of average number, abundance and frequency of occurrence. The presence of vegetable is evidence of a high flexibility of this species in relation to the feeding behavior. Maybe the differences in the social behavior between sex are important in the total amount of ingested food.
