Is it just me or does it help seeing the dark scales on the forehead to ID?
Yup, full blood Coppernose!
Fitz: Natives have the black scales on the forehead a lot of the time too. The Coppernose can have them further down the body sometimes. The Natives can also have the spots further down but it is usually more controlled. But if a Native and a Coppernose cross, the spots can end up everywhere! It is one of my favorite variants. I have countless pictures of them but I won't spam this man's post, here are a few examples.
Picture 1 is a Native Bluegill and the other three are Native Bluegill and Coppernose Bluegill mix.
