A very sought-after fish is the Copperband Butterfly fish, but mostly for what it can do rather than for its looks. Copperbands are known to consume aiptasia, the pest anemones we do not want in our tanks. The problem is that many come in with zero appetite and die in our tanks. I highly recommend you put this fish in quarantine for 30 days, to observe it for disease as well as to give it a chance to recognize daily feedings of mysis without competition from other fish. Each day, feed at the same time a small amount, and within a few days it will soon be devouring them. A fish that eats tends to be a healthy fish with a good immune system. Copperband Butterfly fish will zip in and out of the rockwork, and avoid altercations with other fish if at all possible. Reef-safe
