Redfin Butterflyfish

This image of a pair of redfin butterflyfish (Chaetodon lunulatus) was taken by NOAA photographers in the waters off the coast of Fiji. Known also as an oval butterflyfish, this species is found in the Pacific Ocean from Eastern Indonesia to the Hawaiian islands. The redfin butterflyfish is found at depths up to 65 feet (20 meters) in coral-rich lagoons and semi-protected reefs. It grows to a maximum length of 6 inches (15 centimeters), and feeds exclusively on coral polyps.
