Description
A boldly patterned triggerfish with a tan to cream body, bold black and white diagonal bars, blue and black stripes across the snout, a yellow cheek band, and orange-gold hatching on the flanks. It is a hardy, personable show fish that constantly rearranges rockwork, grunts audibly, and grows territorial with age, so it needs a large tank with a cave it can wedge into using its locking dorsal spine. Keep it in a fish-only or FOWLR system with sturdy aquascaping and tankmates of similar size and attitude, and feed hard-shelled foods to wear down its ever-growing teeth.

Behavior
The Picasso Triggerfish is known for its territorial and aggressive behavior. It may attack and bite other fish, especially those that wander into its territory. Despite this, it is also known for its intelligence and can be trained to recognize its owner and respond to feeding times.
