Description

The Indian butterflyfish has a yellow body which has two broad, black oblique bands which run across the flanks.[2] There is a black eye band which shades to orange below the eye.[3] The pelvic fins, dorsal, anal and caudal fins are yellow.[2] The dorsal fin contains 8 spines and 18-20 soft rays while the anal fin contains 3 spines and 14-15 soft rays. This species attains a maximum standard length of 14 centimetres (5.5 in).[4]

Distribution

The Indian butterflyfish has a scattered distribution across the Indian Ocean and has been recorded from the Cocos (Keeling) Islands and Christmas Island in Australia, the Maldives Islands, Mauritius, Réunion, Amirante Islands and Cosmoledo Island in the Seychelles and the Chagos Archipelago in the British Indian Ocean Territory.[1]

Habitat and biology

The Indian butterflyfish is a species of relatively deep water, living at depths between 22 to 80 metres (72 to 262 ft), commonly at 50 to 68 metres (164 to 223 ft). It has been encountered in small groups of up to 5 individuals on the steep outer drop-offs of reefs, in rubble areas and among areas where black coral and sea fans grow. It is an oviparous species which forms pairs to breed.[4] This species feeds on zooplankton and benthic invertebrates.[1]

Taxonomy

The Indian butterflyfish was first formally described in 1860 by the German-born British zoologist Albert Günther (1830-1914) with the type locality given as Mauritius.[5]

Utilisation

The Indian butterflyfish commands a high price in the aquarium trade because this deep water species is infrequently collected.[1]
