Africa: present in Lake Malawi basin (Ref. 1878, 52161, 55909, 96560), Juba system (1440) and Ruvuma River (Ref. 1440, 97286). Status Tana River population is uncertain (Ref. 52331). Reports from the Lufira River, Upper Congo River basin (Ref. 1440, 26190), are misidentifications of Labeo rosae (Ref. 96560).
非洲: 鑑定的兩者標本來了剛果河流域的從上游 [=剛果], 更特別的, Lufira 河。 它的地理分佈現在被認為延伸到一些東海岸河 (Juba 系統) 。 進一步的收集可能將產生來自中間的地點的標本。 已知不來自凌波波河或奧塔萬戈河流域。 (參考文獻 1440)

Found in shallow water over sandy bottoms (Ref. 5595, 52161). Is a mud-feeder (Ref. 52161), feeds from the biocover and sediment on the sand (Ref. 5595). Also caught using weirs and baskets; formerly very abundant in Malawi, but now rare except where rivers drain undisturbed soil; possible that silt prevents development of eggs (Ref. 4967). Indications that it may leave the lake and run up rivers to spawn (Ref. 52161).
也使用鱼梁与篮子捕捉。 (参考文献 4967) 发现于浅水区沙质底部之上了。 从在沙子上的附着生物与沉淀物觅食。 (参考文献 5595) 从前非常丰富在马拉维中, 但是现在稀有的除在哪里河排水沟未受到干扰的土壤。 可能的那一个淤泥避免卵的发展。 (参考文献 4967)

Spawns in small, muddy wet season rivers leading to swampy dambos (Ref. 2781). Holds its spawn until the rivers flood. 非洲: 鑑定的兩者標本來了剛果河流域的從上游 [=剛果], 更特別的, Lufira 河。 它的地理分佈現在被認為延伸到一些東海岸河 (Juba 系統) 。 進一步的收集可能將產生來自中間的地點的標本。 已知不來自凌波波河或奧塔萬戈河流域。 (參考文獻 1440)
