Melon Butterflyfish, Chaetodon trifasciatus Park 1797

More Info

Distribution	Australian territories of Cocos (Keeling) Islands and Christmas Island. Elsewhere the species is widespread in the Indian Ocean, from East Africa to the Raja Ampat Islands, West Papua, Indonesia. Inhabits protected coral-rich areas in lagoons and on seaward reefs.
Features	Dorsal fin XIII-XV,20-22; Anal fin III,18-21; Pectoral fin 13-15; Lateral-line scales 30-39. Body depth 1.5-1.8 in SL.
Feeding	An obligate corallivore - feeds on polyps from a wide range of different coral species.
Fisheries	Although frequently collected for the aquarium trade, this species usually starves in captivity because it feeds only on live corals.
Similar Species	The similar Pinstripe Butterflyfish, Chaetodon lunulatus, has a white caudal peduncle (vs yellow in Chaetodon trifasciatus) and the back and rear of the body are not as bluish. C. lunulatus occurs in the East-Indo-west-central Pacific.
Species Citation	Chaetodon trifasciatus Park, 1797, Trans. Linn. Soc. Lond. 3: 34. Type locality: Bengkulu Province, Sumatra, Indonesia.
