Found in the same habitat as its prey, Oreochromis, but can also be found over open sandy floors and sometimes near rocks or in the open water (Ref. 5595). Diet consists of scales from the caudal fins of shoaling species of Oreochromis (Ref. 267).

发现于如同它的猎物一般的栖息地, Oreochromis了, 但是也能被发现于开放的沙底部上与有时在岩石的附近或在开放水域中.(参考文献 5595) 食物由浅滩 Oreochromis 的种的来自尾鳍鳍的鳞片组成。 (参考文献 267)

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  4.4   ±0.80 se; based on food items.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
