The Titan Triggerfish is the largest species of triggerfish found on the reef, reaching a massive Max Size of 75 cm. It has a heavy, robust body with a yellowish-green base and dark scale centers that create a "honeycomb" look. Its face is often marked by a dark "mustache" and large, independently moving eyes. In the wild, they are famous for being fiercely protective of their nests, even attacking divers. In captivity, their sheer size and destructive power make them suitable only for the largest custom-built aquaria or public displays.
