The red phoenix/bishop were developed by a farm called fishes of Burundi. They developed most of the different looking tropheus seen on
The net e.g golden Bemba, star spotted duboisi, golden kariza, red bisop and the albino brichardi.
The red bishops that are bred in Europe came from the same farm but have been developed further by breeders but the ones that went to Asia didn't. The Asian trops are also called fire fox duboisi to give it their own twist. The truth is not clear but the pheonix is apparently a line bred fish from caramba. There are also pictures of golden looking trops that looks like the red pheonix bred from a group of caramba. The original breeder has more from the group now.
