Etymology: Orthochromis: Greek, ortho = straight + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment / Climate / Range
Freshwater; benthopelagic. Tropical; 3°S - 6°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 4967)
(total): 16 - 20. Scales on chest and belly are abruptly different in size compared to those on flank. No scales on cheek.
Africa: endemic to Malagarasi River, in Burundi and Tanzania (Ref. 28906).
Essentially riverine with tendency to colonize quieter waters; near bands of reeds and vegetation fringing the river; very small eggs, plant and insect debris and small crustaceans found in stomach; most probably a mouthbrooder (Ref. 28906).

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=0.01479 (0.00690 - 0.03171), b=2.97 (2.80 - 3.14), based on LWR estimates for this (Sub)family-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 (21 of 100) .
