The Pakistan Butterflyfish, also known as Red-tailed Butterflyfish, Collare Butterflyfish, or Redtail Butterflyfish, has a rich brown to black color with light spotted scales throughout. Its mask-like head includes two white bands with a black band through the eyes. The tail is most distinct with a wide red band followed by black and white bands.

The Pakistan Butterflyfish eats stony corals in the wild and care should be taken when housing it in a reef aquarium as it will nip at many sessile invertebrates that grow on live rock.
