I agree with some of the posts above. I have purchased copper bands and other butterflies from Divers den and Blue zoo (pretty much favorite sites) but each one didn't survive because I couldn't get them to eat. In my opinion, this is a fish you need to see healthy at a LFS you trust where you can watch how well it eats. I finally was able to get one my LFS had for about 4 weeks and he was a great eater. When I got him home, he was shy at first but would pick at myssis shrimp from my hand. Now he still only eats from my hand but he eats clams and myssis and bloodworms. I have had him for close to a yr now. (fingers crossed)
