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).
在河中生活在砂质底部之上。 通常形成鱼群。 主要日行性.(参考文献 9086) 吃 Moraceae ， Myrtaceae 的果实与种子， Euphorbiaceae; 鞘翅目，直翅类，鳞翅目与 黄体短平口鲶［Brachyplatystoma flavicans］ ;(参考文献 9086) 而且在浮游生物，游泳生物与甲壳动物上.(参考文献 10615)
