This fish is known as Bluelined Triggerfish, Gold Back Triggerfish and the correct latin name is 

Pseudobalistes fuscus. The Blueline Trigger is highly sought after for its unique coloration and impressive adult size along with its ease of care when kept in a proper aquarium environment. 

Juvenile specimens have a bright yellow or yellowish-tan body with bright blue lines all over its body, along with yellow markings on blue fins. As they grow the contrast between the yellow body and blue lines begins to lesson, and as mature adults they will have a tan body with less distinct blue markings throughout their body. They have the typical Triggerfish anal and dorsal fins, along with a crescent shaped tail fin.                                                                                                                                  

Bluelined Triggerfish are a hardy and aggressive predatory species that are best suited for large aquariums (300 gallons or larger) with other large aggressive fish species. This species is also known for rearranging aquariums by blowing sand and substrate looking for invertebrates to eat and for undermining the foundations of rocks and coral. Also be aware that triggerfish are notorious for biting through tubing, and even heaters, so it is worth thinking very carefully about where you place your equipment.

Due to a very belligerent and highly territorial nature, keep only one specimen per tank, and not with any other Triggerfish species. Smaller fish will end up on the menu, so only choose tankmates of similar size and disposition (i.e. large, boisterous fish that can hold their own). 

Bluelined Triggerfish should be fed a varied diet consisting of many different types of meaty foods including: chopped shrimp, squid, clams or fish. It is also good to provide frozen foods that contain marine algae and are enhanced with vitamins and minerals. This species should be fed at least 3 times a day to provide it with adequate nutrition and to decrease its aggressiveness towards its tank mates.
