This species is omnivorous, that feeds mainly on seeds, as well as terrestrial and aquatic insects. Inhabits streams and ponds between 1 and 100 m asl, in waters ranging from stagnant to swift current at temperatures ranging from 21 to 32 °C. It is usually found in pools and backwaters, where it usually hides among roots, or in caves and undercuts (Ref. 122421).
