Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Écologie
; eau douce benthopélagique. Tropical
Africa: known only from the catchment of Lake Natron in Tanzania (Ref. 32272, 118638).
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 6.2 cm SL mâle / non sexé; (Ref. 32272)
Épines dorsales (Total) : 13 - 14; Rayons mous dorsaux (Total) : 11 - 13; Épines anales: 3; Rayons mous anaux: 9 - 12. Diagnosis: A very small slender species with a wide mouth with broad lips bearing numerous teeth (Ref. 118638). Mature males have dark-edged dorsal and anal fins, iridescent blue-white spots on flanks, white lips, and a spotted caudal fin edged in pink; male breeding dress shows geographic variation, with some populations having yellow bellies and throats, while others are white (Ref. 118638). Females and non-territorial males are sandy-coloured, paler ventrally, sometimes with numerous vertical bars (Ref. 118638).
A maternal mouthbrooder: males defend spawning territories among rocks in shallow water (Ref. 118638). Potential as an aquarium fish (Ref. 118638).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.

Résilience (Ref.
120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
