I purposely introduced some CNBG from Harbin Fish Farms in Central KS in hopes of limiting BG reproduction some-as Cody suggests "may" happen. I can't confirm that but with RES present, it's made for some interesting colors and some fast growing sunfish.
It seems the opercular tab is the best indicator of purest vs mixed/hybrid, or at least that is what I'm finding in common with other more visible ques.
