Copperband Butterflyfish
Chelmon rostratus
 
The Copperband Butterflyfish is a difficult fish to keep and is recommended only for experienced saltwater hobbyists.  The Copperband Butterfly fish is best introduced to an established reef environment that has been stabilized for months. Acclimation to a new home in your tank may take quite some time. This butterflyfish is a beautiful fish and where appropriate makes a great addition to your tank. It's colors are riviting and watching it swim along the rocks is a fantastic treat. It's long snount appears to be specifically designed to reach deep into cracks in the rocks to retrieve a meal.
