识别要点

White to pale yellow body with a single large black teardrop/oval spot on the upper flank just behind the dorsal fin
Bold black vertical eye stripe across the face with yellowish body and dark-edged fins
Classic butterflyfish shape: laterally compressed, pointed snout, and continuous dorsal fin

栖息地

Shallow coral reefs, reef slopes, lagoon patch reefs, and outer reef edges; most common where live hard coral is abundant.

饵料备注

Rarely targeted by anglers; do not target for food. In aquarium capture contexts, tiny reef-invertebrate imitations or frozen coral-feeder substitutes are used, but wild capture is best avoided.

行为

Diurnal and active around coral heads, often in pairs or loose groups. It pecks at coral polyps, algae, and small invertebrates on the reef surface and is wary in open water.

注意事项

Contains reefs with sharp coral hazards; live coral habitat is fragile and often protected. Not a food fish and should not be harvested from reef areas without confirming local rules.

钓法备注

Not a recreational game fish. If observed for study or photography, approach slowly and avoid casting onto coral; use light tackle only if local regulations and collection permits allow, which is uncommon.
