Etymology: Rubricatochromis: Name from rubricatus, Latin for red coloured, refers to the bright red colouration on body of most species when in dominance or broodcare; and chromis, a common ending for African cichlid fishes (Ref. 128620).
More on author: Gill.

Issue
Species boundaries in the genus Hemichromis remain unclear (Ref. 81260).

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).

Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 14 - 15; Raios dorsais moles (total) : 10 - 12; Espinhos anais: 3; Raios anais moles: 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01585 (0.01335 - 0.01882), b=2.96 (2.91 - 3.01), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.64 se; based on food items.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Assuming tm<1 and multiple annual spawning; Fec = 713 mean fec).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
