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).
也使用魚樑與籃子捕捉。 (參考文獻 4967) 發現於淺水區沙質底部之上了。 從在沙子上的附著生物與沉澱物覓食。 (參考文獻 5595) 從前非常豐富在馬拉威中, 但是現在稀有的除在哪裡河排水溝未受到干擾的土壤。 可能的那一個淤泥避免卵的發展。 (參考文獻 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)
