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.
