The Pakistani Butterfly (Chaetodon collare), also known as the Red-Tail Butterfly is a regal fish found among the west Indo-Pacific Ocean. They have a grey or brown body with lighter, golden scale colorations, along with a dark face, white streak behind their gill, and a red caudal fin. They reach a maximum size of 7 inches and should be kept in an aquarium of at least 100 gallons. They do best in peaceful FOWLR tanks, as they do eat coral. Their diet should consist of omnivorous preparations, fed daily.
