Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335).

Issue
This species is placed in the genus Mbipia Seehausen & Bouton, 1998 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.

Dorsale stekels (totaal): 15 - 16; Dorsale zachte stralen (totaal): 9-10; Anale stekels 3; Anale zachte stralen: 9 - 10; Wervels: 28 - 30

Inhabits exclusively the shallow waters (0-2 m) of gently sloping small rock boulder shores, particularly surf protected habitats like small bays. Adult males keep territories at 0.5 m depth under the roots of floating reed mats, but also in large and deep pools between the rock stacks. Found over stone-sand mixed substrate. Feeds mainly on filamentous algae, but takes also insect larvae.

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

A polygynous female mouth brooder with maternal parental care. Males seem to be territorial and sometimes chase other fishes. Brooding females have been observed in very shallow water under roots of floating reed. In the aquarium, females release their fry after about 21 days but continue to keep them in the mouth in situations of danger and at night, for up to another 17 days. Size at 50% maturity not precisely known, but above 12.3 cm SL at the Makobe Island (Lake Victoria, Tanzania).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.6 ±0.27 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).
