Chaetodon collare, also known as Pakistan Butterflyfish, Red-tailed Butterflyfish, Collare Butterflyfish, or Redtail Butterflyfish, has a rich brown to black color with light spotted scales throughout. Its 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. Normally Chaetodon collare grows to 15 cm (6 in.) in length. He is found in the Philippines and Indonesia, and the Indian Ocean,. They are often found in groups or pairs, although in captivity they may act aggressively to members of their own species.
In the wild Chaetodon collare eats stony corals 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. Pakistan Butterflies should be provided with plenty of hiding places. They are normally best kept in pairs singly with plenty of swimming room. The Pakistan Butterfly is considered to be quite hardy but not generally considered to be reef safe.
Chaetodon collare requires a varied diet including marine fish, crustacean, brine shrimp, small invertebrates, fish eggs , filamentous algae and frozen meaty food. Once acclimated to the aquarium, it requires feedings several times daily.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.
