I think it is a hybrid sunfish and likely not from the F1 generation (first generation hybrid); probably reproduction from other hybrids.
Yea, I think you might be right about that. I found a site with a fairly thorough description/visual of the various pure strain panfish and it doesn't quite match any of them. At this point I've stocked 37 fish from this pond and I would estimate that 10 of them looked similar to this. The rest looked like your typical bluegill. I may regret this "bucket stocking" approach. The lady said she knows of 3 species that have been stocked, pure BG, native RBS, and the HBG I mentioned earlier, so no telling what kind of crazies I have. Sounds like the pond has been stocked for 20+ years so these may be generation F82.
Based on my reading I got the impression that the hybridization would eventually revert back to the original species. Is that not the case?
