The Raccoon Butterflyfish (Chaetodon lunula) is also called the Crescent-Masked or Lunule Butterflyfish. This Butterflyfish is one of the easier ones to keep. Given plenty of places to hide, it will settle right in to a non-aggressive tank.
The major hurdle for this fish is to get it to eat tank fed foods, making it important to observe the fish eating before buying it. Offering the fish frozen Mysis Shrimp seems to help them get started. Also, if other fish in the tank are eating certain foods, the Auriga seems to pick up on the fact that the food is edible.
