As far as species to consider, I would definitely utilize the brassy minnows. It will be interesting to see how they fair once predation occurs. Northern redbelly dace, Phoxinus eos are another option. They spawn on mats of FA. Again, they may not fair well under heavy predation. Finescale Dace, Phoxinus neogaeus would be another species found in your area preferring similar habitat.
I think the key here is to allow a reasonable amount of aquatic vegetation to cover your pond. 30%-40% would allow refuge for your forage. Then limit the amount of predators and never allow them to become too abundant if you wish to utilize these native forage species.
Just to confuse us, the academics have changed the Phoxinus genus to Chrosomus recently.
