Main Ref. Val, A.L. and V.M.F. de Almeida-Val, 1995
Remarks 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). Piscivore (Ref. 76754); however, it consumes insects during the dry periods of the year (Ref. 27188).
