my blenndy let mine clean him once so now the cleaner follows him around like a lost puppy. It so funny to watch because the blenndy will go hide in a hole to get rid of the cleaner and and he'll just sit there and wait for the blenndy to pop his head out, i think the blenndy gets mad at him following him wherever he goes but he wont bite the cleaner no matter what he does. :happyfish
