Habitat

FishBase records the species across the Indo-West Pacific in tropical waters. It occurs on clear coastal and protected outer reefs with rich invertebrate growth, typically in pairs and often in deeper reef zones at depths of about 20-40 m.

Tank requirements

  • Minimum tank volume: 200 L (about 53 gal)

Diet

The KB record classifies the Redtail Filefish as an omnivore fed about twice daily. Within the genus Pervagor, related species take algae and small benthic invertebrates; specific prey items for this species were not detailed by the consulted sources.

Compatibility

The KB record describes it as a peaceful, mid-water species but notes it may nip corals, so it is treated as not reef-safe. Suggested tankmates include tangs, wrasses and cardinalfish; aggressive triggers should be avoided.
