Gregarious and non-aggressive (Ref. 27188). Prefers calm zones of main rivers where the vegetation hangs over the river banks. Feeds on the leaves of river plants (Ref. 12225). Possesses powerful dentition that can cause serious bites. Its reproduction has not yet been carried out in captivity (Ref. 27188).

群居而非侵略性.(参考文献 27188) 偏爱植物垂悬在河岸上方的主要河川的平静区域。 吃河川植物的树叶。 (参考文献 12225) 持有能引起严重的咬的有力的牙齿。 它的繁殖尚未被成功完成在繁殖场。 (参考文献 27188)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

The red hooked anal fin of the female is actually a plough. The male has a bilobed anal fin which is designed to wrap around the female's "hook". During spawning, the female inserts the hook into the substrate (e.g., gravel) and ploughs a furrow while laying the eggs with the male in a position next to her with his bi-lobed fin wrapped around the hook as he fertilises the eggs. The female's "hook" is suprisingly strong and can be pushed into coarse gravel (up to the anal opening) without any problem with a shaking body action, the male's bilobed hook folds under the same pressure so they can work in unison (Ref. 55767).南美洲: 亞馬遜河與奧里諾科河河流域; 北方與東方的圭亞那遮蔽河。
