The Picasso Trigger has a wacky, painted appearance. It has a tan body with gradient dark bands, and vibrant blue and black stripes on the top of the head, with a yellow stripe from cheek to cheek and deeply set-back eyes.
They can vocalizes using a "grunting" sound.
An aquarium with rocks and caves provides a good habitat for the Picasso Triggerfish, however, it will tend to rearrange the landscaping and rocks.
The Picasso 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.
