Haplochromis sp. "blue obliquidens" hasn't been described yet but all its morphologics features including dentition are similar to Haplochromis obliquidens versu stricto, the main difference is the body color being blue in this species while H.obliquidens is yellow with a red dorsal band in (Seegers and al.2008). The "blue obliquidens" lives mainly in shallow waters over rocks where emerged plants have their roots in the water at Makobe island, he is the most abundant cichlid encountered in this particular habitat. Blue Obliquidens is rarely seen beyond a depth of 2 meters. It shares it's habitat with some other algae scrapers like Neochromis omnicaruleus, N.rufocaudalis, H.cyaneus, H.flavus, Mbipia lutea, M.mbipi, N.gigas. This is a prolific species with a bright blue body color and red fins that can be housed in a 55 g tank without any problems.
