The Goldback Trigger, Xanthichthys caeruleolineatus, also known as the Golden Back Trigger, is best kept in a large tank with plenty of live rock and free swimming space. Undoubtedly the centerpiece of your aquarium, the Goldback Trigger will be an active and fun-to-watch tank member. They will eat a primarily carnivorous diet and may scour the tank for small inverts. The Goldback Trigger is one of the rarest and most beautiful trigger species available in the marine trade.
