I have a few Koi and a comet goldfish that was in my mom's pond. For some reason she cannot grasp the idea of them surviving the winter so she brought them inside. They're too cramped now in a 55 gallon and she is moving and doesn't want to mess with them. You can have them and a nice big bag of their food too. Just let me know. I'm not sure exactly how many koi but they're pretty nice and all are different, I believe they were purchased at Aquarium Adventure.
