I would like to see the fish you are trying to breed. Their genetics will play a big part of what you will see in the fry. You will get some that will pull more directly from the father and others that will pull from the mother's side. You will see a mix of the two with a mix of the couple's features. Such as mother's body and pearling but the father's head... So pics of the parents would help. The pics below will show you what I mean.
Father (GM)


Mother (ZZ/GM)

Off spring from the same batch. Male #1 pulled more from the mother side. Some the father traits came out when he became full grown.
Male #1 size 6 inch

Male #1 size 10 inch

Male #2 pulled more from the father's side.
Male #2 size 5 inch

Male #2 size 8 inch

This Female from the same batch pulled almost directly from the father.

I hope this helps a bit. Good luck on your project.
