It looks dominantly a faded Amphilophous (rd/Midas).
When a fh crossed to a pure breed, most likely the pure breed gene take over a lot because they are whole and strong... I think this is a FH x RD. See the old fading flower line? Midas or RDs dont have flowerlines like that. They have big spot in the middle, small spot at the tail, and vertical bars..And the gill area is really pink in contrast with orange. That's 3 colors. Should be just orange/white
Im trying to say pure breed gene will most likely dominate if bred to FHs because they are 100% of one kind which is solid. FHs have small percentage of many unknown kinds and crossed so much they are weakened. If you mix it up, you'll have more pure breed gene running around strong and most likely will dominate in the making of the batch. But Anything can happen on rare occasion so Im not saying that's always the case.
Oh and the mother's gene is the stronger gene from breedings I have seen. so if the mother is a FH, you get better chances if you want it to look more FH
