Common in black and clear water streams and rivers, as well as lagoons and other off-channel habitats associated with whitewater rivers (Ref. 52916). Prefers slow currents and a silty or sandy bottom. Like other species of the genus, it is a formidable predator (Ref. 12225). Strict piscivore; however, it consumes insects during the dry periods of the year (Ref. 27188).
