Environment

Freshwater; brackish; benthopelagic; pH range: 6.5 - 7.5; dH range: 4 - 16; potamodromous (Ref. 51243)

Climate / Range

Tropical; 21°C - 23°C (Ref. 1672), preferred ?; 11°N - 4°N

Distribution

Africa: widely distributed in West Africa, where it is known from most hydrographic basins (Ref. 53405), associated with forested biotopes (Ref. 5644, 52307). Also reported from coastal basins of Cameroon, Democratic Republic of the Congo and Nile basin (Ref. 7378), but at least its presence in Cameroon is unconfirmed in Ref. 81260. Ref. 52307 limits this species to Guinea, Sierra Leone and Liberia. Species boundaries in the genus Hemichromis remain unclear (Ref. 81260).

Short description

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 10-12; Anal spines: 3; Anal soft rays: 8 - 9. Diagnosis: 3 black blotches on sides, the first on opercle, the second at midpoint of body, the third on caudal-fin base; upper profile of snout convex or straight (Ref. 53405).

Occurs in mud-bottomed and sand-bottomed canals (Ref. 5723); some distance inland from the coast, associated with areas of intact or recently disturbed forest cover. Considered the true 'jewel fish' of aquarists, this species is also used as an experimental animal by physiologists and ethologists (Ref. 5644). Attains a maximum of 12 cm in captivity. Aquarium keeping: aggressive; in pairs; minimum aquarium size 100 cm (Ref. 51539).

IUCN Red List Status (Ref. 115185)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.5002 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.9 ±0.64 se; Based on food items.

Resilience (Ref. 69278)
High, minimum population doubling time less than 15 months (Assuming tm<1 and multiple annual spawning; Fec = 713 mean fec)

Vulnerability (Ref. 59153)
Low vulnerability (19 of 100)

Price category (Ref. 80766)
