The Barred filefish is another ubiquitous species distributed across the Indo-Pacific region up to 32 degrees north and south of the equator.

Barred filefish are armed with spines on their dorsal and anal fins that they can lock into position, presumably making them awkward for predators to swallow. They are common in surface waters around oceanic islands and offshore coral reefs. They may be found patrolling their home range on Turtle Reef either singly or in pairs. The male can be distinguished from the female by its brighter colored spines (4) at the base of its tail. This is a shy species that usually retreats quickly into caves or large crevices when approached by divers. Sometimes they will warn divers not to approach by flicking their dorsal spine. They are omnivores feeding on algae as well as tips of branching corals, sponges, sea urchins, and mollusks.
