In a stocking with cc, it may have been hybrid bluegill and over time, some Fx offspring will look a lot like green sunfish.

scotjute, you can actually get these species for stocking, or just catch/net some from another BOW? If you have to buy any, why not stock hybrid bluegill? Agressive for fishing, will not overpopulate as pure breeds will, will control skeeters, will have more meat on them. Take handsfulls of feed chunked at them.
