Chaetodon nigropunctatus, the black-dotted butterflyfish, is a species off marine ray-finned fish, a butterflyfish, belonging to the familyChaetodontidae. It is found in the north western Indian Ocean.
Chaetodon nigropunctatus has a whitish mouth set in a grey face, the colour of the body is greyish white and it is marked with many longitudinal rows of dark grey spots. The tail is black with a white margin.[4] The dorsal fin has 13 spines and 21-23 soft rays while the anal fin has 3 spines and 18-20 soft rays. This species attains a maximum total length of 14 centimetres (5.5in).[3]
Chaetodon nigropunctatus occurs at depths between 1 and 40 metres (3.3 and 131.2ft),[1] inhabiting coral reefs where they occur in pairs. They are thought to feed mainly on coral polyps.[3] it occurs over reefs, either of coral or rock, and sometime in Sandy lagoon areas.[1]
Systematics
Chaetodon nigropunctatus was first formally described in 1880 by the Frenchpaleontologist, ichthyologist, and herpetologist Henri Émile Sauvage (1842-1917) with the type locality was given as Oman.[5] It belongs to the large subgenusRabdophorus which might warrant recognition as a distinct genus.[6]
Utilisation
Chaetodon nigropunctatus is rare in the aquarium trade.[1] However, it is a difficult species to keep in captivity due to its specialised diet of live coral polyps.[4]
