Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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。
