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).
形成移动缓慢的鱼群那一个只吃浮游动物。 藉着两者雄鱼与雌鱼成鱼，父母亲的口孵非常普遍; 幼鱼, 大约 6 mm SL, 独自口孵雌性。 与父母分开了的幼鱼被发现与其它的丽鱼科的窝例如 长体雅丽鱼［Lepidiolamprologus elongatus］ 在一起与 小鳞奇齿丽鱼［Perissodus microlepis］ 。
