Help with what to breed with blood parrots and what to do with too much aggression.

[Aquatic Aggression]

Well you could try breeding it with a flowerhorn to produce a kirin parrot.

Not how that works friend. You could try breeding it with flowerhorn then line breeding for 4 years and you might get a kirin parrot.
Do you really want to breed these fish? I mean you dont have a plan or anything. Just crossing random fish is a big waste of time if you want good fry.

My bad. I have little experience with breeding hybrids.

I have very rarely seen a male bp that is sterile

I think you meant, fertile. The male BP is most likely shooting blanks.

Yes that is what I meant.
