The copperband butterflyfish (Chelmon rostratus), also known as the beaked coral fish, is found in reefs in both the Pacific and Indian Oceans.

[2] The fish appears taller than its length because of its compressed, deep-bodied form with a long dorsal and posterior fins as well as its vertical yellow stripes on a white background.

[citation needed] They do well at a normal reef temperature range of 75 to 84 °F (24 to 29 °C), with a tank size of at least 75 gallons and plenty of live rock to graze on.

Many aquarists introduce the Copperband Butterfly just to get rid of these pests without giving consideration to their long term needs for survival.

This is not a recommended fish for inexperienced aquarists, as it requires excellent tank conditions to thrive or even survive.
