+1 for indjo
Personally I dont see anything wrong with the pair besides form. Of course the female should balance out the form more since that is what females pass on most. While males pass on mostly color for offspring.
Your fry wont have very good form, but it will be acceptional. They aren't different in type because they're both short finned. Just one is HMPK and the other is PK(male).
You aren't going to get PERFECT fry, but of course you need to start somewhere when breeding. You just aren't going to get perfect stock (unless you buy from Karen Mac Auley of course) This is exactly what I said on the first thread.
Good luck OP and keep us updated.

I'd breed them - keep the mother in a rather small container to stunt her growth and boost fry's growth. Take the best (to your preference) fry and breed back to mom. If you let mom grow further, fry might not be able to out grow her in time.
As for aggressiveness - I prefer them aggressive. Non aggressive female might hide more which will make aggressive males attack .... more risky. Aggressive female usually spawns faster. Just make sure that she is in breeding mode when you release her - older/bigger giants females are often harder to breed and males can be more deadly.
