I'm with snrub. Pure GSF or GSF hybrid.
Well Gents,
If you are correct, then that is unexpected and somewhat disappointing news as I originally stocked CNBG & RES (as well as minnows). My forage base was small in size (2-3") when I stocked last fall. When I found these specimens, I was wondering how they could have gotten off a spawn before winter. It seems to be making sense now. Yes, I also noticed the mouth was a bit too big for a BG or RES. Now, I've got other questions.
I kept these fish and have them in a small tank. Their pigment is returning. I can shoot you a better pic shortly. Thank you, for your help.�
