Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Female incubates eggs in her mouth. Parental care is exercised for a short while after hatching when the juveniles move off to shallow grassy areas and there they remain, in the Upper Zambezi, until floodwaters recede and force them back to the main river. They seek refuge in lagoons and backwaters until reaching a size large enough to avoid predation by tigerfish in the open waters of the river.非洲: 在剛果與尚比亞的庫內內河流域 (安哥拉與那米比亞) ，奧塔萬戈河，尚比西河上游與 Kafue 河 (安哥拉，那米比亞，波札那，尚比亞, 辛巴威), 與 Luapula-Moeru(剛果河流域)。
