Blue Triggerfish.

The blue triggerfish or rippled triggerfish, Pseudobalistes fuscus, is a brilliant blue colour. This fish is known for its aggressiveness and many divers choose to stay away from them, as they bite often.

Tropical Indo-Pacific, Red Sea.

Coastal waters, shallows in the open, 3-50 metres (10-165 feet)

55 centimetres (22 inches)

The blue triggerfish, like most other triggerfish, eats shellfish, small crustaceans, and other bottom-dwelling invertebrae.
