Dusky Butterflyfish
Chaetodon flavirostris
The Dusky Butterflyfish is a reef-associated butterflyfish of the Indo-Pacific, recognized by its dark body and yellow snout. It feeds mainly on coral polyps, small invertebrates, and benthic algae, and is generally not a targeted angling species.
Identification points
- Dark dusky-brown body with a paler underside
- Bright yellow snout/face contrasting with the body
- Butterflyfish profile with a small mouth and rounded, laterally compressed shape
Habitat
Coral and rocky reefs, reef flats, lagoons, and seaward reef edges; often in shallow to moderate depths where live coral and mixed invertebrate-rich structure are present.
Bait notes
Not a standard gamefish. If encountered by anglers, it may peck at tiny natural baits such as shrimp, clam, coral-dwelling worms, or small pieces of squid; small reef flies and micro-jigs can also draw strikes.
Behavior
Usually encountered singly or in pairs, picking food from reef surfaces during the day. It is cautious around divers and anglers and is more a reef browser than a pursuit predator.
Caution
Reef-dwelling fish in its range may carry ciguatera risk if eaten from tropical reef areas; local advisories should be checked. Handle carefully around coral to avoid cuts and habitat damage.
Fishing notes
Best treated as a photographic/observation species rather than a harvest target. If attempting to catch one, use ultra-light tackle, tiny hooks, and minimal bait near reef structure; release promptly to avoid stress and reef damage.
