Balistoides viridescens

The titan triggerfish, giant triggerfish, or moustache triggerfish (Balistoides viridescens) is a large species of triggerfish found in lagoons and at reefs to depths of 50 m (160 ft) in most of the Indo-Pacific, though it is absent from Hawaii. With a length of up to 75 centimeters (30 in), it is the largest species of triggerfish in its range (the stone triggerfish, Pseudobalistes naufragium, from the east Pacific is larger). The titan triggerfish is diurnal and solitary. It is usually wary of divers, but during the reproduction season the female guards its nest, which is placed in a flat sandy area, vigorously against any intruders. Divers should swim horizontally away from the nest rather than upwards which would only take them further into the territory.
