Copperband Butterflyfish, Chelmon rostratus, is often found living on or around the reefs of the Indian and Pacific Oceans. Members of the genus Chelmon make gorgeous inhabitants of fish only aquariums. Soft Corals and most Invertebrates should do fine with the Butterflyfish, but it may damage Stony Corals, as they are a part of its natural diet. Peaceful or non-aggressive tankmates are recommended to reduce stress on the Butterfly. When Butterflyfish are first introduced to the aquarium, they may refuse to eat. Should the fish continue this behavior for three or more days, live food should be offered (if not from the beginning). Food soaked in a garlic product will often entice the Butterfly to eat. Another useful method to encourage some Butterflyfish to eat is to place their food inside of a coral skeleton. Groupings of Butterflyfish can be introduced simultaneously in the same aquarium, making a stunning display. It is best to make sure that the fish have plenty of aquarium space each when adding a group. Live Rock and multiple places to hide also helps to reduce stress in a group introduction situation.
