Body shape (shape guide): fusiform / normal; Cross section: compressed.
Occurs over sandy bottoms in rivers. Usually forms schools. Mainly diurnal (Ref. 9086). Feeds on the fruits and seeds of Moraceae, Myrtaceae, Euphorbiaceae; Coleoptera, Orthoptera, Lepidoptera, and Brachyplatystoma flavicans (Ref. 9086); and on plankton, nekton, and crustaceans (Ref. 10615).
Males and females spawn in groups; often two or more males curled around one female (Ref. 10612).
