Description

A deepwater planktivorous triggerfish with a silvery-lavender body, a broad golden-yellow dorsal saddle, and fine blue-edged horizontal lines along the flanks, with males showing red-orange margins on the tail. Unlike most triggers it hovers in open water rather than digging, and is comparatively mild-mannered, though large adults still assert themselves over tankmates. Give it a long, deep tank with strong flow, ample open swimming space, and secure rockwork with a cave for sleeping; a heavy lid is wise as startled triggers can leap.

Reef Safe

With caution

Environment

Behavior

This species is generally active and can be quite curious. It is known for its intelligence and can sometimes be seen rearranging the aquarium decor.
