Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態學
; 淡水 底中水層性. 熱帶
Africa: known only from the catchment of Lake Natron in Tanzania (Ref. 32272, 118638).

Maturity: Lm ? range ? - ? cm
Max length : 5.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 32272)
背棘 (總數) : 13 - 14; 背的軟條 (總數) : 9 - 12; 臀棘: 3 - 4; 臀鰭軟條: 9 - 11. Diagnosis: A very small slender species with a narrow ventrally-placed mouth (Ref. 118638). Mature males have dark-edged dorsal and anal fins, iridescent blue-white spots on flanks, white lower lips, and a spotted caudal fin; male breeding dress shows geographic variation, with males of some populations having yellow throats and white bellies, while others are a fiery orange underneath (Ref. 118638). Females and non-territorial males are sandy-coloured, paler ventrally, sometimes with faint vertical bars (Ref. 118638).
It inhabits the springs and some spring-fed creeks near the southern and south-eastern shores of Lake Natron (Ref. 32272). It co-occurs with Alcolapia alcalicus and Alcolapia latilabris (Ref. 32272). Observed to nibble at stones and gravel, probably taking mainly algae for food; omnivorous, taking insects from the water surface as well (Ref. 32272). A maternal mouthbrooder: males defend spawning territories among rocks in shallow water (Ref. 32272, 118638). Potential as an aquarium fish (Ref. 118638).
棲息於在湖天然碳酸鈉的南方而東南方海岸附近的泉水與小溪。 它以 O. alcalicus 與 O. latilabris 共同生存。 觀察在石頭與礫石細咬, 可能主要地帶藻類作為食用魚。 從水面也的雜食性又動人的昆蟲.(參考文獻 32272)
