Ecología
; agua dulce; salobre bentopelágico. Tropical; 24°C - 28°C (Ref. 2059); 23°N - 7°S
Africa: Coastal rivers of Kenya from the Mwena River to the lower Athi below Lugard's Falls; also near its mouth, including Lake Chem Chem; Lower and middle Tana River, Northern Uaso Nyiro, Juba system and Webi Shebeli; Nguruman; and Ethiopia (Ref. 5166). Probably also in Lake Momello, south of the Kenya-Tanzania border (Ref. 5166, 118638). Three subspecies are recognized: Oreochromis spilurus niger, Oreochromis spilurus percivali and Oreochromis spilurus spilurus.

Max length : 19.2 cm SL macho / no sexado; (Ref. 2); 16.3 cm (female)
Espinas dorsales (total): 14 - 17; Radios blandos dorsales (total): 10-13; Espinas anales 3; Radios blandos anales: 9 - 10; Vértebra: 28 - 30. Scales on cheek in 2 or 3 series. Genital papilla of male conical or club-shaped, with a sub-terminal pore. Females and immature males have a yellow-buff background color with a series of mid-lateral blotches and a more dorsal parallel series. Mature males golden-yellow; conspicuous bright blue areas on dorsal, anal and pelvic fins; orange or red dorsal lappets.
Feeds on insects, plants and diatoms (Ref. 2).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Spawns in shallow water with shelving bottom in ponds. Size of first spawning depends on population density (lower at higher densities). Mating pit is the size and shape of a saucer. Eggs probably fertilized before being taken into the mouth by the female, or are fertilized inside the mouth (Ref. 2).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00846 - 0.04293), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.6 ±0.35 se; based on food items.
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (tm<=1: multiple spawning per year).
Fishing Vulnerability (Ref.
59153): Low vulnerability (18 of 100).
Nutrients (Ref.
