Pundamilia cf. azurea was previously known as Haplochromis sp. "blue nyererei". It was described as Pundamilia azurea by Seehausen & Lippitsch in 1998. This is a little species growing to only 10 cm. It exhibits variations in morphology and color just like other species inhabiting the rocky habitat. It lives in crevices at moderately steep to steeply sloping areas with large boulders from the shallow waters at the shoreline to a great depth. It is known from many islands of the central Speke gulf but with a scattered distribution, probably linked with the presence of Pundamilia pundamilia in their micro habitat. When P. pundamilia is abundant, P. azurea tends to occupy the greater depths (more than 12 m) to not enter in competition with this larger species. Males are territorial, while females move in large schools foraging in the substrate to find food. Even in the wild this fish is quite rare, in spite of its stunning colors and prolific broods. The population around Ruti Island is mostly blue-black with white dorsal, anal and caudal fins. The population around Mabibi Island is dark blue with red anal and caudal fins. One should not house P. azurea with P. pundamilia or P. macrocephala in the same tank because this species is less aggressive and less territorial these two species.
