Sometime back, the question was raised as to whether or not anyone had ever encountered a pond containing stunted RES. I can't be absolutely sure, but I THINK the consensus from the masses was no?
In my opinion however, I think it's possible given the right circumstances. I have caught RES that featured huge eyes, large fins, and stretched out body dynamics. But I have never caught them in numbers from the same BOW.
Of course, I also have never fished an all RES pond. (No predators)
