species: Chaetodon trifasciatus
Chaetodon lunulatus ������������������������������������������is widespread in the Pacific and extends into the eastern Indian Ocean while Chaetodon trifasciatus is found only in the Indian Ocean. Both species occur at Christmas Island in the Indian Ocean and they hybridise there. The species are distinguished by the colour of the caudal peduncle (yellow in Chaetodon trifasciatus, white in Chaetodon lunulatus) and by the dark eyestripe continuing over the head in Chaetodon lunulatus but not in Chaetodon trifasciatus (Montanari et al, 2011). Older records of Chaetodon trifasciatus from Lizard Island are thus likely to be misidentified specimens of Chaetodon lunulatus.
Comments
Chaetodon lunulatus Quoy and Gaimard, 1825 is a valid name. Chaetodon lunulatus Shaw, 1803 is a different species, a synonym of Chaetodon lunula (Lacepede, 1802) (ITIS, 9 May 2012)

Distribution and habitat preferences
Areas of rich coral growth.
Found in most reef habitats around the island.
Behaviour
The Redfin Butterflyfish is specialist hard-coral feeder, taking polyps from a wide range of coral taxa including Acroporid, Pocilloporid, and Poritid corals. It is usually seen near areas of good hard coral cover, and upon maturation fish form monagamous pairs which remain together thereafter.
