They're Badidae. All by themselves. They are close cousins of the ancestor of all the labyrinth fishes. Probably their ancestors were related to cichlid ancestors somewhere before the close of the Jurassic. These are Laurasian fishes; cichlids got started in Gondwana.
This is the fish I want. (well, I want Altum Angels, but wantn' ain't gittn!) Wantn' ain't gittn' me far with finding these beauties either. Anyone in the NYC area want to split the costs of a shipment?
