A friend recently ordered koi angels through the mail. When they arrived, they looked just like some of the babies that Lindsay Buckingfish and Stevie Fishnick have had. Actually, what my friend received were white marble angels.
A white marble angel is an angelfish that is predominantly white but has some black markings. They can have a golden or orange crown. In my case, Lindsay Buckingfish, a black marble, and Stevie Fishnick, a golden angel, both have golden or orange crowns. So their offspring have the same bright crown.
But a true koi angelfish is one that is predominantly bright orange, just like the koi they are named after.
