thanks for your comment. Certainly I've found them as peruvian altums tooI think they likely are. They look similar to Altums in some respects. They used to be sold as Peruvian Altums, which they are not. There is no such fish. However, they are still a very nice looking angel and you should be happy with them.
thanks for your reply, I think both names refer to same fish, although there are another species of Pterophyllum in PeruThose are most likely Rio nanay angels. Peruvians don't have dots from what I know. They look nice, they get nicer as they get older
