I used to keep a Juvy native tank I'd go open the mino trap and populate my tank. 1 year later release and replace. Keeping them at full size is not as much fun as watching them grow year after year. I'd keep Green sunfish, northern pike, Bullhead rock bass, Large mouths. Lots of fun at feeding time ^_^
You should decorate the tank with drift wood instead of the plastic stuff. Go to the forest preserve pick up lighter colored wood, bake it, and power wash it, to remove bark, rot and parasites(order isn't really that important). Should be good to go and would look way cooler.
