Order:	Perciformes  (perch-likes)
Class:	Actinopterygii (ray-finned fishes)

Climate:	tropical; 22 - 26°C
Global Importance:	fisheries: minor commercial; aquaculture: commercial; aquarium: commercial
Resilience:
Distribution:	Africa: Wami River system (Tanzania) and Zanzibar (possibly introduced). Widely introduced. At least one country reports adverse ecological impact after introduction.
Diagnosis:	Dorsal spines (total): 16-18; Dorsal soft rays (total): 11-14; Anal spines: 3-3; Anal soft rays: 9-12; Vertebrae: 29-30. Jaws of mature males become enlarged resulting in a concave upper profile. Females and non-breeding males silvery or steel-grey with 2-4 mid-lateral blotches and a more dorsal series usually evident. Mature males almost entirely black; lips pale or black; margin of dorsal fin and margin or upper half of caudal bright red, pink or orange. Deep preorbital bone.
Biology:	Occurs at 26.5 °C (Ref. 2). This species is occasionally territorial. In the saline ponds of Zanzibar, Oreochromis urolepis hornorum was feeding on unicellular algae and detritus, including decayed fragments of macrophytes. Although filamentous algae and small invertebrates were present in the ponds they were not ingested (Ref. 2)
