Whitespotted Filefish
Cantherhines macrocerus
Whitespotted Filefish (Cantherhines macrocerus) is a reef-associated filefish of warm tropical and subtropical seas, usually seen singly or in pairs around coral and rocky structure. It is not a major game fish, but it may take small natural baits or tiny lures when feeding near cover.
Identification points
- Pale white spots scattered over a mottled brown to olive body
- Very compressed, angular body with a small pointed snout
- Long first dorsal spine that can be raised like a trigger, with a small tail fin
Habitat
Shallow coral reefs, reef edges, rocky bottoms, jetties, and rubble zones, often where sponges, algae, or other benthic growth provide cover; commonly from nearshore shallows to deeper reef slopes.
Bait notes
If targeted at all, use very small pieces of shrimp, squid, clam, or crab; tiny soft plastics or micro-jigs can also draw strikes. It is more of an incidental catch than a regular target species.
Behavior
Slow, cryptic, and deliberate, it picks at algae, small invertebrates, and fouling organisms around structure. It relies on camouflage and usually moves cautiously, often hovering close to reef cover rather than chasing prey.
Caution
Handle carefully: filefish have rough, leathery skin and a sharp first dorsal spine that can poke or snag hands and nets. Follow local reef-fishing and marine-protected-area rules; consumption guidance is limited and local advisories should be checked.
Fishing notes
Fish light tackle with small hooks and minimal weight near reef structure, pilings, or ledges. Present bait close to the bottom or just off the reef face with a subtle retrieve; avoid heavy gear that spooks fish in clear water.
