Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Spawns in shallow water with shelving bottom in ponds. Size of first spawning depends on population density (lower at higher densities). Mating pit is the size and shape of a saucer. Eggs probably fertilized before being taken into the mouth by the female, or are fertilized inside the mouth (Ref. 2).非洲: 在 Lugard 的秋天之下的對 Athi 下游的肯亞從 Mwena 河的沿海的河川; 也在它的嘴的附近, 包括湖 Chem Chem; Tana 河下游與中游, 北方 Uaso Nyiro ， Juba 系統與 Webi Shebeli; Nguruman。 可能也在湖 Momello 中, 肯亞南方-坦尚尼亞毗鄰。
