If you're gonna use fatheads, be sure to put in some approptiae structure for their spawning. I have two wooden pallets fixed together and slightly weighted down with cinder blocks, so they (FH) have a flat surface to hold their spawn. I put three of these 'spawning pallets' in my 3/4 A. pond. They went nuts. They will spawn 'several' times and get your forage built up for your LMB.
