Gephyrochromis lawsi

Gephyrochromis lawsi is a monotypic genus representative — the only species in Gephyrochromis — and one of the more scientifically interesting mbuna due to its unique morphology. The species has evolved notably enlarged, fleshy lips adapted for a specific feeding technique: pressing its mouth flush against steeply angled or overhanging rock surfaces to scrape biofilm and soft algae. This lip specialisation is uncommon even among the highly adapted mbuna.

Found across the rocky shores of northern and central Lake Malawi, G. lawsi is a moderately sized mbuna with males displaying blue-grey body colouration with subtle darker markings. The species is not brightly coloured by mbuna standards, but its scientific uniqueness and rarity in the trade make it highly sought by cichlid specialists.

In the aquarium, Gephyrochromis lawsi requires a tank with rough-surfaced rockwork on which biofilm can develop. Flat smooth rocks will not satisfy its natural feeding inclinations. It is moderately aggressive and can be integrated into a mixed mbuna community. Dedicated keepers working with specialist mbuna genera will find this species both fascinating and rewarding.
