Occurs in shallow, intermediate habitats where the bottom is mainly sand with some rocks (Ref. 46829). Forms slow-moving schools (Ref. 26454) of sometimes more than 1.000 individuals (Ref. 26454, 46829). Feed exclusively on zooplankton (Ref. 26454, 46829) and pick out individual organisms with their rather protractible mouths (Ref. 46829). Parental mouthbrooding is very common by both male and female adults; the young, of about 6 mm SL, are solely mouthbrooded by females; young which had become separated from the parent are found with other cichlid broods e.g. Lepidiolamprologus elongatus and Perissodus microlepis (Ref. 26454).
形成移動緩慢的魚群那一個只吃浮游動物。 藉著兩者雄魚與雌魚成魚，父母親的口孵非常普遍; 幼魚, 大約 6 mm SL, 獨自口孵雌性。 與父母分開了的幼魚被發現與其它的麗魚科的窩例如 長體雅麗魚〔Lepidiolamprologus elongatus〕 在一起與 小鱗奇齒麗魚〔Perissodus microlepis〕 。
