To much glare on pic to tell. But I would guess --not all BG (depending on what "bluegill" means).

Can't tell on many for sure. The bottom right one is a male CNBG. Up one row and to the right looks like at least part RES. I would think that they are mostly CNBG. Not sure there are any BG in south Fla. unless they were transplanted from the north country ( say about Tallahassee). \:D

Next up -- what do you think.
