Copperband no longer eating

Try raw clam or mussel as Crimper has suggested. I had a CBB for I think 6 years that loved them in addition to its regular diet of Mysis. I never bothered cutting up the mollusks, I just pried them open then threw them into the tank. More importantly though I believe they need a large and very mature system with lots of naturally occurring prey items to choose from, especially while settling in. Once established I discovered that I had to feed mine at least 3 times a day otherwise it would start sampling coral.
