Looking for some input here.

As I sort my tilapia I have found a handfull with bright red, almost fire red tails. This is not disease or parasite or toxin caused.
Clearly a genetic development in the phenotypes that I have not had before.
Orange/red bodies sure....but the actuall tail fin? And why not the rest of the fins?

Has anyone else had this? I am curious to know if I can narrow this trait down and cross it back to my orange/red Tilapia and make the whole fish red......ideas?
