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 in most of the Indo-Pacific, though it is absent from Hawaii. With a length of up to , it is the largest species of triggerfish in its range (the stone triggerfish, ''Pseudobalistes naufragium'', from the east Pacific is larger). ==Behavior==
The titan triggerfish is diurnal and solitary. It feeds on sea urchins, molluscs, crustaceans, tube worms and coral.〔 It often feeds by turning over rocks, stirring up sand and biting off pieces of branching coral. This is why other smaller fish species are often seen around it, as they feed on the detritus and smaller organisms that are stirred up. Titan triggerfish have been observed being aggressive to other fish who enter their territory.
