I caught a bunch of these the other day. I've been fishing 40+ years and I have never caught them before. I THINK I know what they are but they are not known to be in this water body. I was fishing a river eddy below a papermill dam on the Wisconsin River in Central Wisconsin.
Here are some details:
the eyes are NOT red,
the ear is like a bluegill,
the body shape of a rock bass,
the belly colorations of a pumpkinseed,
anal fin and tail is heavily edged in a dark red-orange,
pectoral fins are orange in color,
the mouth is larger than a bluegill, basslike,
beautiful neon blue streaks on the face and cheeks.
