Etymology:
Chromidotilapia:
Greek, chromis = a fish, perhaps a perch + Bechuana, African native thiape = fish (Ref.

;
mrac:
Named after MRAC, the abbreviation for Musée Royal de l'Afrique Centrale, Tervuren, Belgium, one of the most important institutions working on African fishes (Ref.
47112
)
.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Africa: Ogooue and Nyanga basins, and coastal regions north of Libreville, Gabon (Ref.

). Monogamous (Ref.

Larvae
Chromidotilapia mrac
is a monogamous, pair bounding female larvophilic mouthbrooder, which spawns in caves (Ref.
47112
). Eggs are incubated by the female alone for 3 days, after hatching the larvae are carried by the female for 9-10 days in the buccal cavity (Ref.
47112
). When free swimming the juveniles are protected by the adults for a duration of about 4-5 weeks (Ref.
47112
).
