I have added fathead and rosey red minnows, along with other forage (snails, clams and crayfish), channel cats, bluegill, crappie, yellow perch. I have a decent population of largemouth bass. I may add several Northern Pike and walleye, I'm undecided as of yet. Additionally, as I have an algae problem so I recently added 5 large koi, for a total of 7, in the hopes that they will help control the weeds.
