Are the three females you mentioned the only breeder sized females you have?
What is your ultimate goal for that project down the line? If you have a goal, that is.
Myself, I'm hoping to get a fire girl up to size this year; as well as pick up another. One I would like to breed to my yellowbelly fire, with the goal of producing a black eye leucistic. Something I've always wanted. The other I would like to breed to my orange dream, because that combo goes together very well. Especially as you start mixing it with more mutations.
Personally I would shoot for an orange dream. They're a great morph to have in your collection.
