Thanks everybody. It's okay with me to just say it's a sunfish and leave it at that. I personally think it's a pumpkinseed due to the tiny red dot at the edge of the colored circle, but it's only visible in one of my pictures. That's interesting that they hybridize. Makes perfect sense. And also, I could have taken pictures of more than one fish, although that was not my intention. The one with the red dot showing, maybe that's not the same fish as the other pictures. I was trying to follow one but the water was muddy. So, sunfish, possibly pumpkinseed, possibly green. I'm satisfied.
