Little is known of its biology in its natural environment. Unlike most Characoids, this species is typically solitary and territorial. The dimensions of the mouth confirms its predatory habits. Its food consists mainly of Ephemeroptera larvae, copepods and ostracods. In the aquarium, only the male guards the spawned eggs. About a hundred eggs are deposited on the substrate and dispersed by the male (Ref. 12225). Reproduces by laying eggs on stones or submerged leaves (Ref. 27188).
它的自然環境的它的生物學特性少為人知。 不像大多數的脂鯉類,這種典型獨居性的與具有領域性。 嘴巴的尺寸確定它的掠食性習慣。 它的食物主要地蜉蝣仔魚,橈腳類的動物與介形蟲組成。 在水族館,只有雄魚保衛魚卵。 一百卵被沈澱在底部上面而且散佈藉由大約雄魚.(參考文獻 12225) 藉由在石頭或水下的樹葉上產卵繁殖。 (參考文獻 27188)
