Eastern triangle butterflyfish

It is found in the central Indo-West Pacific region from the Cocos-Keeling Islands and Indonesia in the eastern Indian Ocean to Fiji and Tonga, north to southern Japan, south to New Caledonia and New South Wales in Australia.[2][3] It grows to a maximum of 16 cm long.The body has a pattern of alternating cream and grey-brown to purple chevron-shaped bars.[2] The eastern triangle butterflyfish is found in seaward and lagoon coral reefs.[2] The triangle butterflyfish (C. triangulum) is its western sister species, replacing C. baronessa in the Indian Ocean.If Chaetodon is split up as some researchers propose, this group might go into Megaprotodon as other high-backed and square-bodied species, but its exact relationships are still not well known.
