背面の脊椎 (合計): 14 - 16; 背鰭 (合計): 12-15; 肛門の骨 3; 臀鰭: 7 - 8; 脊つい: 28 - 29. Diagnosis: upper lateral line extending full length of dorsal fin base and descending a row before proceeding length of three or more scales; 14-15 gill-rakers, widely spaced along lower limb of first arch; 36-40 lateral line scales; head length 29.0-35.7% of standard length; usually 29 vertebrae; inferior vertebral apophysis short and oriented caudad rather than of standard Tylochromis type (Ref. 52346).
Opportunistic benthic macrophage (Ref. 52346). Mainly feeds on plants and insects (as well as their larvae) (Ref. 52307). Female mouthbrooder (Ref. 52307, 52346) that does not pair-bond (Ref. 52307).
