Masked Bannerfish
Heniochus monoceros
Masked Bannerfish (Heniochus monoceros) is a reef-associated butterflyfish of the Indo-Pacific, noted for its tall white dorsal filament and facial mask. It is not a common angling target and is usually encountered by divers or reef observers rather than anglers.
Identification points
- Broad black diagonal mask through the eye on a mostly white body
- Single long black dorsal filament trailing from the first dorsal spine
- Black-and-white banding with a yellowish rear body and tail
Habitat
Shallow coral reefs, reef slopes, lagoons, and drop-offs, usually close to branching corals and surge-swept reef edges in clear tropical marine water.
Bait notes
Not a regular game fish and generally not targeted. If accidentally hooked, small fine hooks with tiny shrimp or squid strips may take it, but better viewed than fished for.
Behavior
Feeds on small benthic invertebrates and zooplankton picked from the water column and reef surface. Often occurs singly or in pairs, hovering near coral heads and turning sideways in current to intercept drifting food.
Caution
Reef fish; avoid capture and handling around coral to prevent injury to fish and reef. Consumption is not a normal use, and ciguatera risk cannot be dismissed for small reef fish from tropical reefs.
Fishing notes
If fishing near reef habitat, use very light terminal tackle to minimize injury and release immediately; avoid casting into coral structures. This species is better appreciated by snorkeling or diving than by angling.
