Inhabits sand and gravel runs, sandy and muddy pools and backwaters of small to large rivers (Ref. 86798). Less frequent in lake and impoundments (Ref. 86798). Larvae feed on cladocerans, copepods, and midge larvae, while juveniles consume fishes (Ref. 10294). Spawn between March and June (Ref. 10999) in pairs or small aggregations (Ref. 11003).
