Amphilophus is in there, but it would be Midas (A. citrinellus) not red devil (A. labiatus). So hard to say what the origin is in some of these line bred FH.
Funny, the following vendor lists one of
my fish from years back (a LFS midevil) as a Golden Phoenix Flowerhorn. WTF? LOL Not only did they steal my image, they got the fish ID wrong, in fact, way wrong.
