Barred Filefish
Cantherhines dumerilii
A rare reef-associated filefish from the Indo-Pacific, usually seen alone or in pairs around coral and rocky bottoms with good algal growth. It browses on small benthic invertebrates and algae rather than chasing fast prey.

Identification points
- Laterally compressed, oval filefish body with a small pointed snout
- Distinct dark bars/markings across a pale to brownish body
- Long first dorsal spine that can be raised like a trigger
Habitat
Coral reefs, reef slopes, and adjacent rocky areas in warm tropical Indo-Pacific waters, especially where shelter and attached growth are abundant; juveniles may stay close to complex cover.
Bait notes
Not a standard angling target. If encountered incidentally, small natural baits such as bits of shrimp, squid, or crab may interest it, but it is more often observed than caught; tiny reef jigs or small soft plastics near structure can also draw strikes.
Behavior
Slow, deliberate swimmer that picks at algae, tunicates, and small invertebrates with a small terminal mouth. Often relies on camouflage and may hold position near structure instead of moving far.
Caution
Handle carefully because filefishes have rough skin and a sharp, erectile first dorsal spine that can poke. As a reef species, local consumption advisories and size/collection rules may apply; check regulations and avoid taking fish from contaminated reefs.
Fishing notes
Use very light tackle and work slowly around coral heads, bommies, and rubble edges. Because it is not a common game fish, most catches are accidental on reef tackle; avoid destructive methods and release promptly if landed.
