Replaced by its close relative the Peppered butterflyfish (C. guttatissimus) in the Indian Ocean, these two species are sympatric from Christmas Island to Bali.[3][4] C. punctatofasciatus is the type species of the subgenus Exornator[5] and was first formally described in 1831 by the French anatomist Georges Cuvier (1769–1832).The dorsal fin has a yellow margin and there is a bright orange patch running through the caudal peduncle.[2] It is found in coral-rich areas and clear waters of seaward and lagoon reefs.This fish feeds on filamentous algae and coral polyps and other benthic invertebrates.
