I stocked HBG, BG, and Redear and I get crosses that look like all of those but I'm not sure what the crosses are. It seems the GSF genes are pretty dominate in mine. Caught the biggest one so far last week. 11 and 1/2 inches long and very well filled out but long bodied instead of rounded like a bluegill. Those crosses with GSF genes will bite when nothing else will and they eat a lot of Aquamax. About all of them have red on their ear lobes and yellow coloring in their fins.
