The Linespot Triggerfish (Xanthichthys lineopunctatus), also known as the Striped Triggerfish, can be found throughout the Indo-Pacific ocean. They have a grey-silver body with dashes and spots, along with a vibrant orange caudal fin. They are an extremely rare find in the aquarium trade, and have become a gem among enthusiasts. Juveniles hide among reefs and rockwork, while adults scavenge singly for food. They sleep perched among rocks and coral, or may bury themselves in sand to hide. They feed on a variety of invertebrates, including sponges, worms, crustaceans and sea urchins. They should be fed a well balanced diet of vitamin-enhanced mysis, as well as occasional sea weed for extra nutrients. They should be kept in an aquarium with at least 125 gallons with fish of similar size and temperament.
