Genomic data of the copperband butterflyfish, <i>Chelmon rostratus</i>

The copperband butterflyfish (<i>Chelmon rostratus</i>), also known as the beaked coral fish, is found in reefs in both the Pacific and Indian Oceans. The butterflyfish is one of the three species that make up the genus <i>Chelmon</i> and all have long beaks. These fish are easily identified by the yellow banding and long snout. The young fish are similar in appearance to adult fish. Butterflyfish grow up to 20 cm in length.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. The snout is long and slender, and the dark eye of the fish is less conspicuous than the dark eye-spot on the dorsal fin. The base of the tail features a dark band that runs perpendicular to the tail. Butterflyfish may be distinguished from the similar <i>C. marginalis</i> by their color pattern and number of dorsal fin rays. <br>Copperband butterflyfish are found at depths of 125 metres either alone or in pairs. These fish form monogamous pairs during breeding. They are usually found on coral reefs or rocky shorelines, and also in estuaries and silty inner reefs. This species is territorial and oviparous.
