It occurs in streams with moderate current and with sandy and clayey substratum. During dry season, this species is found in deeper parts of the streams, usually shaded by vegetation. It also inhabits marginal lagoons and flooded regions of great rivers. Can tolerate moderately salt water in some lagoons and estuaries. Diurnal, feeding preferentially on diptera larvae, macrophytes, cladocera, hirudinea and some aquatic ascaris (Ref. 85206).
