Issue
This species is placed in the genus Gaurochromis Greenwood, 1980 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). We keep all the lacustrine and riverine "Haplochromine" species of the Lake Victoria catchment in the genus Haplochromis Hilgendorf ,1888 following Van Oijen et al. (1996: Ref. 12750), until a new complete taxonomic revision is published.

Occurs over shallow water with a soft mud bottom. A few specimens have been caught over sand (Ref. 4983). Feeds mainly on insects (esp. larval Diptera) and mollusks ( particularly the bivalve Corbicula, although some gastropods like Melanoides are also eaten (Ref. 558).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [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).
Trofisch niveau (Ref. 69278):  3.1   ±0.34 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
