I know this thread is a few months old but i fish at this small pond not far from my house here in gloucester VA and its loaded with these hybrids. Ive been fishing there for a few years and most of the time im strictly fishing for sunnies. Ive fished around the entire pond and the only sunfish that ive pulled out are tons of greensunfish, redears,bluegil and these hybrids.. No pumpkinseeds, its not imposible that i just havent caught any yet but like i said i fished this pond for years. The small hybrids look identical to the one posted but the bigger more mature ones have a longer spot on there gil plate, Almost like a redbreasted sunnie does. And ive tried them in my native tank and they are very VERY aggresive/territorial. Its forsure part greensunfish but i really dont think the other half is pumpkinseed..
