Gold Back Trigger: Male

Xanthichthys caeruleolineatus. In the home aquarium, which should be no less than 250 gallons, they require a meaty diet, e.g., fortified brine shrimp, mysis, chopped fish, shrimp, squid, and clam flesh, and/or meaty type frozen carnivore foods with two or three feedings per day. Food with hard shells should also be placed in the aquarium, as they will nibble on the shells which will keep their teeth ground down.
