I think youll like them (Pumpkinseeds)they are like Cichlids that can endure the cold. Pleeease dont get Channel catfish.....they get around 25-50lbs and up to three and a half feet long here in Misssouri and will eat your Koi when fully grown. Bullheads dont get big enough to eat adult Koi and the young ones can have spots in their coloration (plus they can be taught to eat out of your hands). I wish you lots of luck and fun times with your pond!
