Titan Triggerfish at Surin Islands Thailand

An inquisitive Titan Triggerfish (Balistoides viridescens) seen whilst on a No Troubles Just Bubbles liveaboard scuba diving trip at Thailand's Surin Islands, near the border with Myanmar. Luckily for the divers, this individual was not nesting, because the Titan Triggerfish can be very aggressive during the nesting period.
