I've received a CK from a friend who is going away to college. It's about 11" and for the first 4 days, glided around checking out his new digs. I also received about 50 rosies as feeders. I fed the rosies for the first 4 days and on the fifth, there were no rosies to feed; the CK ate every single one in one evening. Will feeding him fewer but larger fish keep me from stocking that many feeders? Incredibly voracious fish; I really thing he's quite cool!
