Identification points

Yellow body with a large black oval band over the eye and upper body
A prominent dark spot on the hind upper flank, giving a 'eclipse' look
White to pale rear body and dorsal/anal fins with contrasting dark edging

Habitat

Shallow coral reefs, reef flats, lagoon patch reefs, and seaward reef slopes, typically where live coral and rubble are abundant.

Bait notes

Not a standard gamefish and rarely targeted by anglers; if collected, tiny marine invertebrate baits such as live shrimp pieces or reef-scraped worms are more relevant than fish baits. Small micro-jigs or flies that imitate coral-associated prey are more appropriate than conventional tackle.

Behavior

Diurnal and wary, it picks at coral surfaces and reef rock for polyps and small invertebrates. It often swims in pairs and stays close to complex cover.

Caution

Avoid collection in protected reef areas, and do not consume unless local regulations and reef-fish advisories allow it; small reef fish can accumulate ciguatera risk depending on location.

Fishing notes

Best approached with very light, delicate gear around reef structure, but catching it is usually incidental and not recommended. Handle minimally and release quickly if taken.
