; 淡水 底中水层性; 河川洄游 (Ref. 51243). 熱帶; 13°S - 22°S
Africa: lower and middle reaches of the Zambezi River system, including the Shire and Lake Malawi (Ref. 26190). Also in Lake Mweru and the Luapula (upper Congo River basin) (Ref. 26190). Range thought to extend to some East Coast rivers (Rufiji system) (Ref. 1440).
非洲: 三比河系統的下游與中游, 包括雪利河與馬拉威湖。 現在一般認為分佈範圍延伸到一些東海岸河 (Rufiji 系統), 到剛果河上游河與 '剛果' 的 Luapula-Mweru 區域的部份 (參考文獻 1440)

Prefers large rivers but is also found in large lakes and dams (Ref. 52193). It grazes on algae and `aufwuchs' from rocks (Ref. 7248, 52193). From October to December in Lake Moëro, the adults gather and migrate to the spawning grounds; they go up the Luapula River up to the foot of Johnston Falls where they undergo one massive spawning between January and March. This massive spawning of short duration is known as kapata in the Luapula-Moëro system and in the tributaries of the Luapula. This species is intensely fished and caviar is produce from eggs collected during migration from Lake Moëro to Luapula River (Ref. 26190).
偏爱大河但是也被发现于大的湖与水坝。 啃食藻类与来自岩石的附着生物.(参考文献 7248) 从十月到在 Moero 湖的十二月, 成鱼聚集而且回游到鱼卵地面。 他们上升 Luapula 河向上到詹斯顿岛的脚落下在哪里它们在一月与三月之间历经一个大规模的产卵。 这一个大规模的产卵持续很短的时间在 Luapula-Moero 的系统与 Luapula 的支流中即是 kapata。 这种是被密集的渔捕而且卵用来生产鱼子酱在从 Moero 湖到 Luapula 河的迁移的时候收集了.(参考文献 26190)
