We have a 0.5-acre frog pond that is only 4-feet deep that is less than two years old. We put fatheads in last spring, which have done well and multiplied. This Spring we put 250 1-2" redears to grow out until fall so they would not become expensive food for my bass in the other pond. No other fish have been stocked and the pond is land locked. I was looking at it last weekend and was surprised to see a 7-8 inch green sunfish. Had him on a fly twice but lost him and haven't seen him since. He's well fed and fat. I think he was mixed in with the fatheads.
