Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
The spawning site or nest is normally constructed under and against a rock with a diameter of between 50 to 200 cm; the male excavates the sand from beneath the rock and heaps it up, building a semicircular wall around the spawning site; male spawning sites are usually at least 4 meters apart (Ref. 47113).非洲: 馬拉威湖。
