The Undulate Triggerfish, also known as the Orangelined Triggerfish or Orangetailed Triggerfish, has an attractive, emerald-green body with yellow-orange vertical stripes.

A 180 gallon or larger aquarium with large pieces of rock to form caves is ideal. It will rearrange the aquarium landscaping and rocks. It vocalizes using a “grunting” sound. It is a hardy fish, but aggressive towards other fish.

The Undulate Triggerfish needs a varied diet of meaty foods including; squid, krill, clams, small fish and hard shelled shrimp to help wear down their ever growing teeth.
