The aptly named Convict Tangs are distinguished by six vertical black bars against a yellow-green background. One of these bars crosses the eyes, a feature common in many fish, which is thought to help confuse possible predators.
Convict Tangs are usually seen in large schools, again a tactic to deter predators.
