The Goldenback Triggerfish (Xanthichthys caeruleolineatus) with its unique yellow-brown and white coloration and blue stripes is a true gem for any saltwater aquarium enthusiast. Care for the Goldenback Triggerfish is relatively easy, requiring a minimum tank size of 200 gallons to accommodate its needs as it can grow to 14 inches in length. However, be aware of its highly aggressive nature, which calls for careful consideration when choosing tankmates as it will eat most invertebrates and small fish. While not reef safe, this carnivorous beauty will thrive on a diverse diet of marine-based foods such as krill,clams,shrimp, and other frozen meaty marine diets.
