Six crisp black bars on a pale silver-white body, a small black smudge at the tail base, and a mouth that works over rock all day long. It is one of the most effective hair algae grazers in the hobby and one of the very few tangs that naturally shoals, so a group of them moving across the rockwork together is a genuinely different look from the usual single showpiece tang.
