Etymology: Oreochromis: Latin, aurum = gold + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 9°S - 10°S
Africa: Lake Chungruru, a crater lake in the Rungwe Mountains, north of Lake Malawi in Tanzania.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 19.0 cm SL male/unsexed; (Ref. 4967)
(total): 14 - 15;
soft rays: 8 - 11;
Vertebrae: 30. Diagnosis: breeding male black; length of head 37.6-40.5% SL; toothed area of lower pharyngeal with concave sides; median length of bone 1.0-1.24 times its width and 31.6-35.5 % length of head; blade 1.2-1.4 times median length of toothed area; length of lower jaw 32.0-39% head length; teeth of jaws in 4 or 5 rows (Ref. 2).
Like O. hunteri, this species appears to be confined to a single lake without an outlet (Ref. 4967).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00682 - 0.03686), b=3.02 (2.82 - 3.22), in cm Total Length, 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 to moderate vulnerability (26 of 100) .
