My only concern with a WE/YP only pond is if the YP can reproduce enough to keep the WE fed. During the original stocking of FHM, I would also stocking GSH as well... I would give the FHM and GSH a good year of spawning before the addition of YP and WE... Perhaps the use of red shiners as well, they may be an alternative or addition to the GSH and FHM and there are some commercial sources of red shiners in the the Midwest.
