Pond Boss Forums INTRO Questions & Observations Is this a pure GSF or a hybrid?

I'd bet on them being mixed in. I am amazed when I go to pet shops in my area and look at the fish in their tanks. I often see green sunfish mixed in with rosy reds and feeder goldfish. I've seen several species of sunfish mixed in, but mostly greens. Must be cause they are so manly! HAHA
