Thank you ewest! Do you think 3-5 WE will do the trick in about a year? Or do i need to introduce them right away with the RES? How many adults, 50? I did not realize the HSB could spawn in such a small pond, that was the only reason i was thinking of them as an option. I was worried about the WE with higher water temps being located farther south. But our temps are not that different than southern MI being in the mountains here, and i have the constant flow of water plus the deep holes.
