Who has one of these? I'm a potters addict, and after searching long and hard I've found one that eats frozen and flake and DOES NOT eat coral. I've had him for about a month now and before that he was downstairs at a LFS for 3 months because I wanted to make sure he was going to do ok. I hope I'm not cursing myself by posting this, as I'll be VERY upset if he dies, but I was curious if anyone else has had any luck with them
