I don't know anything about Bream, I raise Steelhead trout and some Cats. I put in probbly 4000 fatheads prior to putting in the fish and I cannot believe the amount of second generation fathead minnows i now have. Once you put in the Fatheads and if they have enough cover you should never have to put anymore Fatheads in ever. I have 300 fish in just shy of a 1/2 acre pond and the trout will barely touch the trout feed. I assume they are so full and content with the Fatheads which is a natural feed that the trout feed is just a tasty snack. One thing to remember is when the Fatheads spawn they die soon after and become easy prey for the fish, however their off spring go very rapid and the cycle continues. With my experience i certainly would try some Fatheads and see how you get along.
