Max length : 23.8 cm SL male/unsexed; (Ref. 111115); common length : 14.0 cm TL male/unsexed; (Ref. 10612); common length :18 cm TL (female); max. published weight: 211.00 g (Ref. 111115)
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).
