Prefers lentic waters where the river banks are steep. Feeds on the leaves of river plants. During the short rainy season, a third of its diet consists of flowers and seeds which they find in the flood zones of the forest (Ref. 12225). The small larvae are zooplanktivores. Reproduction is asynchronous and lasts year round. However, spawning frequency is clearly higher during the rainy season. Is a likely candidate for fish breeding studies (Ref. 27188).
偏愛平靜的水域在哪裡河岸陡峭的。 吃河川植物的樹葉。 在短的雨季的時候,三分之一的它的食性由花與他們在森林的洪水區域中發現的種子組成。 (參考文獻 12225) 小的仔魚是吃浮游動物者。 繁殖是非同步而全年度的。 然而,清楚地產卵頻率在雨季的時候比較高。 是一個有可能的候選魚種為魚類繁殖的研究.(參考文獻 27188)
