Etymology: Alcolapia: From Albert Alcock, 1891, edited the research campaigne carried out by the ship Investigator in Bengal and Calcute + Bechauana, Tihape = fish.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: known only from the catchment of Lake Natron in Tanzania (Ref. 32272, 118638).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.2 cm SL male/unsexed; (Ref. 32272)
(total): 13 - 14;
soft rays: 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).
