Taxonomic Remarks
Hemichromis cristatus Loiselle, 1979 is a valid species ad Rubricatochromis cristatus (Loiselle, 1979) after Lamboj & Koblmüller (2022; Ref. 128620). Species summary page to be created.
Milieu: milieu / Klimaatzone / Diepte / verspreidingsgebied
Ecologie
; zoet water; brak water benthopelagisch; pH range: 6.5 - 7.5; dH range: 4 - 16; potamodroom (Ref. 51243). Tropical; 21°C - 23°C (Ref. 1672); 11°N - 4°N
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).

Maturiteit: Lm ?  range ? - ? cm
Max length : 13.6 cm SL mannelijk / geslacht onbekend; (Ref. 8992); common length : 7.5 cm TL mannelijk / geslacht onbekend; (Ref. 12193); max. gepubliceerd gewicht: 10.00 g (Ref. 3799)
Dorsale stekels (totaal) : 14 - 15; Dorsale zachte stralen (totaal) : 10 - 12; Anale stekels: 3; Anale zachte stralen: 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).
Body shape (shape guide): fusiform / normal.
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).
