Lake Malawi - Thumbi West Island

Some eminent authors believe this species to be a geographical variant of the highly variable congener A. stuartgranti rather than a distinct taxon but since most popular resources continue to view it as valid we also list it here. At Masinje it has been observed to show a distinct preference for rocky caves and crevices in relatively shallow (3-6 metres deep) water. This is in contrast to most other members of the genus, which tend to forage over sand, but similar to behaviour seen in A. jacobfreibergi.

Males of this species occur in a wide range of colour forms depending on locality, with blue variants being found predominantly (but not exclusively) towards the north of the lake and yellow in the south. This variation, alongside its relatively extensive distribution, has resulted in some taxonomical issues, several of which have not yet been resolved. For example, two forms from the southwest of the lake are referred to as A. sp. "stuartgranti maleri" and A. sp. "stuartgranti mbenji", respectively, and may turn out to be distinct species given their colour patterns an...
