Coach, I think you would be safe to add the RES this year. Just my opinion, and maybe we can get a few other comments from the guys here. I have asked all over the country, and no one has ever documented a "stunted" redear sunfish population, to the best of my knowledge (and I have asked for years and years). Thus, I think you would be safe. The pumpkinseeds, on the other hand, are like bluegills in their multiple spawning capabilities. I would wait on them. They sure are a pretty fish, though, especially once those males get to about 8 inches!
