Pseudobalistes fuscus (common names: blue triggerfish, rippled triggerfish, yellow-spotted triggerfish and blue-and-gold triggerfish) is a fish belonging to the family Balistidae.[2][3]
Pseudobalistes fuscus can reach a length of 55 centimetres (22 inches) in males. The body is mainly brown, but fins have yellow margins. Juveniles are yellowish brown with a network of brilliant bluish wavy lines. With growth these lines become interconnected.[2]
This fish is known for its aggressiveness and many divers choose to stay away from them, as they bite often.
This species is widespread in the Tropical Indo-Pacific, from the Red Sea to South Africa, Society Islands, southern Japan, Australia and New Caledonia.[2]
Pseudobalistes fuscus is a reef-associated species. It prefers coastal waters, shallow lagoons and seaward reefs, at 30–50 metres (98–164 ft) of depth.[2]
This triggerfish, like most other triggerfish, eats shellfish, small crustaceans, and other bottom-dwelling invertebrae.[2]
