Not sure what BNM is, maybe "bluntnose minnows"? If so, those are similar to fathead minnows. Stock ten pounds of each, and make sure they have spawning substrate...they both like to stick their eggs to the underneath sides of firm objects, boards, rocks, PVC pipe...whatever you have, in shallow water. They'll graze on periphyton, which grows on the underwater substrate you provide. They'll also feed on small organisms growing near the pond bottom. If you can feed them, they'll come to fish food, too.
