Central America: Pacific slope rivers from west of the Sona Peninsula, Panama, to Coto River, north through the Parrita-Quepos region of Costa Rica to extreme west of Mexico, and on the Atlantic slope from rivers of Nicaragua (Managuá lake) and Honduras.
Typical of quiet waters in creeks and shorelines of larger rivers where there is low to moderate current. Found in slightly brackish waters at sea level and in waters up to 610 m elevation, though generally more abundant below 200 m. Food consists of fish scales, including those of other characins, cichlid and others, and aquatic insects (Ref. 36880).
