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; 25°C - 26°C (Ref. 12468); 1°N - 10°S
Africa: endemic to Lake Mweru (Ref. 26626). Reports from the lower Congo rapids (Ref. 82335), Lindi (Ref. 82324), Wagenia Falls (Ref. 82324, 106245) and Lualaba (82324) are either unconfirmed and questionable, or belong to other species (Ref. 26626, 106290). Reports from the Kalungwishi and Luongo (Lake Mweru basin, Zambia) refer to other species (Ref. 26626).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
