Justification: The species was rarely caught by the Haplochromis Ecology Survey Team (16 specimens in a period of four years) and disappeared from the catches after 1985. In 2006 the species was observed again (at least two specimens) near Makobe Island in the Speke Gulf by Shinji Mizoiri, Mitsuto Aibara and Norihiro Okada (see Bibliography). More information on the lake wide population trend, distribution and threats to this species is needed before a full assessment can be made. |

Threats [top]
| Major Threat(s): | The main threat to this species is predation by Nile Perch (a potentially reversible threat). It is also potentially threatened by hybridization due to decreased water transparency (on account of eutrophication and erosion leading to increased sedimentation and runoff) interfering with mate recognition visual cues (Mrosso et al. 2003). |
