Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); praecox: The species is named in reference to the reproductive precocity of its members (Ref. 52346).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 5°S - 7°S
Africa: lower Congo River, below the rapids at Matadi (Ref. 52307, 52346).

Morphology | Morphometrics
(total): 14 - 15;
soft rays: 7;
Vertebrae: 28. Diagnosis: upper lateral line extending full length of dorsal fin base and descending a row before proceeding the length of 3 or more scales; 15 gill-rakers along lower limb of first arch; 35-37 lateral line scales; relatively large headed and deep bodied; pectoral fin long, usually extending to level of spinous anal fin (Ref. 52346).
Omnivorous, prefers small organic particles, regardless whether they are plants or small insects (Ref. 52307). Opportunistic bentic microphage; probably tolerant of relatively high salinity levels (Ref. 52346). Maternal mouthbrooder (Ref. 52307, 52346) that does not pair bond (Ref. 52307).
