Someone else was looking for these a couple months ago.
They were common in the club several years back, but have disappeared.
True A. thomasi (African Butterfly Cichlid) is fairly meek for West Africans, so somewhere in the Angelfish range. However, it is commonly misidentified with things like Hemichromis elongatus (5 Star Generals) when small/juvenile which will quite happily terrorize and kill everything in the tank including each other.
And, of course, every fish is an individual which means it might act completely contradictory to everything you have read.
