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.[3] it occurs over reefs, either of coral or rock, and sometime in Sandy lagoon areas.[1] Chaetodon nigropunctatus was first formally described in 1880 by the French paleontologist, ichthyologist, and herpetologist Henri Émile Sauvage (1842-1917) with the type locality was given as Oman.[5] It belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus.[1] However, it is a difficult species to keep in captivity due to its specialised diet of live coral polyps.
