The titan triggerfish, The Clown Triggerfish, Red toothed triggerfish, orange lined tiger fish

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.
The Clown Triggerfish is one of the more popular saltwater fish species but you really need the right aquarium set up to keep them long term.
Red toothed triggerfish are normally deep purple with bluish-green markings on their heads and glowing light blue margins on the tail lobes and fins. Just like other fish in the family Balistidae, the tail is lyre-shaped. The mouth of the triggerfish seems to be grinning and it maintains tiny red teeth that are needle sharp with two teeth in the upper jaw which can be seen when its mouth is closed.
The Orange-lined Triggerfish is found in the Indo-Pacific region growing up to 30cm in length. Found singly and territorial, in lower surge zones, of deep lagoons and seaward reefs
