Inhabits streams and rivers of moderate to high current velocity in 10-640 meters elevation. Swims upstream in search of small tributaries in which to breed; lays eggs in excavated nest in the sandy bottom of creeks. Omnivorous, feeds on fruit, flowers, seeds, insects, annelids, crustaceans, and small fishes (Ref. 36880). Popular fish among sport anglers (Lopez-Pinto, pers. comm.).
