Feeds on algae, small insects and fish eggs (Ref. 52307). Also kleptoparasite of freshwater crabs (Ref. 53950). Ovophilic mouthbrooder with both sexes as possible incubator; from aquarium observations: a few days prior to spawning, both partners remain close together for much of the time; the genital papilla of the female is clearly visible immediately before spawning and is much broader and larger than the male's; females are normally more successful than males when it comes to brooding the fry; when mouthbrooding, which ends about 3 weeks post-spawning, the specimens are relatively shy and prefer to lie silently near the bottom in secluded areas; once free swimming, juveniles normally do not return to the parent's mouth again (Ref. 52307).

Male or female carries the egg in the mouth (Ref. 52307, Ref. 13614). A few days prior to spawning, both partners remain close together for much of the time; the genital papilla of the female is clearly visible immediately before spawning and is much broader and larger then the male's; females normally more succesfull in brooding the fry; specimens are relatively shy and prefer to lie silently near the bottom in secluded areas when mouthbrooding, which ends about three weeks post-spawning; once free swimming, the fry normally does not return to the parent's mouth (Ref. 52307).非洲: 湖 Barombi 的特有種-媽-Mbu ，喀麥隆西方部。
