The Crosshatch Triggerfish, also known as the Blue Cheekline Triggerfish, has a very interesting pattern to its coloration. The body of this Trigger is yellow in color with many dark lines creating a crosshatch pattern. The face of this fish has very distinct blue lines running from the mouth to the back of the gill plate. The fins of the Crosshatch Trigger are a beautiful blue color with yellow borders, and the tail is red.

A 180 gallon or larger aquarium with rocks and caves provides a good habitat. It will rearrange the landscaping and rocks as it wanders in and out of the caves. It vocalizes using a “grunting” sound. The Crosshatch Triggerfish are very friendly and make a great pet as well as a great conversation piece.

The Crosshatch 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.
