Abactochromis is a monotypic genus of cichlid fish containing the single species Abactochromis labrosus (formerly known as Melanochromis labrosus). ^[2] The genus name combines the Latin for "driven away from" ("ab" - away from, "actus" - driven) with the commonly used haplochromine name "chromis". The name encompasses both the origin of the genus (the species was "banished" from the genus Melanochromis ) and the fish's solitary, wandering behaviour (as if it had been driven away from the other cichlids). ^[3]

A. labrosus is native to Lake Malawi. ^[4] The largest known wild specimen (shown in the photo at right) had a standard length (without caudal fin) of 119 mm (4.7 in).
