First pick it looked like a smallmouth bass. then I leaded towards bluegill. Maybe I see warmouth too.
Not tall enough of a body to be a bluegill unless it's a hybrid with a green or Warmouth and that side is dominant. If it is a Warmouth X Green then that's a fish I've been looking for for a long time, Warmouth are my favorite sunfish but unless they're a hybrid with something else you can't own them in PA.
