I have 2 ponds, the smaller being in my front yard. I dug it and started from scratch with only hybrid bluegill (which I fed) just for the grandkids and visitor's kids to fish for. They did great for a couple years and then I started catching strange looking sunfish just like those in your pictures. Big head, big eyes, fat gut, and very small bodies. The state fish biologist said they were from the HBG that reproduced reverting to whatever they were crossed with. They never get enough meat on them to eat no matter how much I feed them. I let a river fisherman seine them out to use for trot line bait.
