The copperband is my favorite fish, but they have a vey dismal survival record in captivity. Most do not accept prepared foods and will just slowly starve to death. They are peaceful and are one of the only butterflies you can keep in a reef. A 75gal tank with a lot of LR
is needed to keep this fish long-term. IF you decide to get one, spend the extra money and get one collected from Australia. Avoid buying one from the Philappeans as the collection methods are suspect. This is a very difficult fish to keep, but if acclimated properly and if you can get it to eat it should do okay.
