Adults occur in ponds. Favored food fish. They are strict herbivores which feed on plant debris, leaves and algae (Ref. 12225) but are reported as omnivores in Ref. 2060. The males are mature at 18 cm and the females at 22 cm (Ref. 12225). Distinct pairs breed on densely grown weedy places (Ref. 205). In the Amazon, the species of this genus are gregarious and undergo migration (Ref. 12225).
出現於池塘。 有利的食用魚。 吃植物殘枝, 樹葉與藻類 (參考文獻 12225) 的是一個嚴厲的草食動物但是參考文獻 2060 被報告為一個雜食者. 雄性是在 18 公分與雌性在 22 公分時成熟。 在亞馬遜河，這一個屬的此魚種是群居的而且歷經遷移。 (參考文獻 12225)
