Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Male starts with the courtship and is the active partner (Ref. 1672). The male makes from the anal fin a sort of cup and the female lays the eggs in this cup (Ref. 1672). The male then spreads the eggs so that they attach, e.g., to plants.非洲: 剛果河流域 (剛果，安哥拉, 喀麥隆);(參考文獻 3188) 魯誇湖流域 (參考文獻 27292) 與坦噶尼喀湖.(參考文獻 4537, 參考文獻 36901)
