Etymology: Orthochromis: Greek, ortho = straight + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical

Maturity: Lm ?  range ? - ? cm
Max length : 7.9 cm SL male/unsexed; (Ref. 28906)
Found in rather slow running water, in a section bordered with dense vegetation and in a small shallow stony brook with rather swift water; seems to be more common in fast flowing water between the stones; detritus eater; female mouthbrooder (Ref. 28906).

Probably a female mouthbrooder as several preserved specimens with eggs or fry in the mouth appeared to be females.
