From 1 to 30 meters.
Habitat: reef-associated. Archer butterflyfish. Attains 20 cm. Feeds mainly on coral polyps and hence difficult to keep in an aquarium. Often seen in pairs on outer reefs between 5 and 20 metres. Tropical Indo-West Pacific from Delagoa Bay to Japan and central Pacific. Seen at Sodwana in May 2007 - has paired up with a Chaetodon zanzibarensis. Neville Ayliffe has seen them many times together during 2006 and 2007. Occurs in lagoon and seaward reefs in areas with rich coral growth . Juveniles may be found in shallow Acropora thickets. Adults occur in pairs. Omnivorous. This species is extremely difficult to maintain in an aquarium and is very rarely sold.

Trends
Population
This is an uncommon species, occurring in low abundance throughout its range (e.g., mean of 0.03 individuals per 200 m2 in Moorea, French Polynesia; Berumen and Pratchett 2006). This species is likely to decline in abundance following coral loss, but it is too rare to reliably sample using standard survey techniques. However, it is widespread and the global population is potentially large. It is usually observed as solitary individuals, but sometimes in pairs (G.R. Allen pers. comm. 2006).

This species relies on live coral for food and/or recruitment, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently, there have been no documented declines associated with coral loss, and there appear to be no other major threats to this species.

Management
Conservation Actions
There appear to be no species-specific conservation measures in place. This species is present within marine protected areas. Monitoring of this species is needed in conjunction with coral monitoring, though it will require specific sampling methods to reliably estimate its abundance. Research is required to establish its specific dietary requirements and reliance on coral.

Bluelashed butterflyfish
The bluelashed butterflyfish, Chaetodon bennetti, is a species of butterflyfish (family Chaetodontidae). It is found in the Indo-Pacific from East Africa to the Pitcairn Islands, north to Japan and south to Lord Howe Island and Rapa Iti.[1]
It grows to a maximum of 20 cm (almost 8 in) long. The body is yellow with a black patch surrounded by a blue circle below the dorsal fin and two curved blue lines above the belly. Its vertical black eyestripe is flanked by two blue lines.[1]
Like the other butterflyfishes with angular yellow bodíes with black eyestripes and (except in the present species) a single differently-colored patch, it belongs in the subgenus Tetrachaetodon. Among this group it seems to be the most basal living species. If Chaetodon is split up, this subgenus would be placed in Megaprotodon.[2]
The bluelashed butterflyfish is found in seaward and lagoon reefs in areas with rich coral growth. Juveniles may be found in shallow Acropora thickets. Adults occur in pairs. This species feeds largely on coral polyps.[1]
