Threadfin Anthias

Pseudanthias huchtii

Threadfin Anthias is a small reef fish from Indo-Pacific coral reefs, best known for its vivid coloration and elongated fin rays. It lives above steep reef slopes and outer-reef drop-offs, where it feeds in the water column on tiny zooplankton.

棲息地

Outer reef slopes, surge channels, and drop-offs over live coral and rocky reef in clear tropical marine water, usually in midwater above the bottom.

誘餌筆記

Rarely targeted by anglers. If caught intentionally, very small planktonic imitations, micro-jigs, and tiny fly patterns that mimic zooplankton are more relevant than traditional baits.

行為

Forms loose harems around reef structure; feeds on drifting zooplankton in the current and retreats into the reef when threatened. Most active in daylight and often stays a few meters above coral heads.

警告

Do not rely on it as a food fish; small reef species can carry ciguatera risk depending on location, and local collection rules may apply in marine protected areas.

釣魚筆記

Best approached with ultra-light tackle in clear water near reef drop-offs or current seams; small white, pink, or orange flies/micro-lures fished gently in the midwater zone may draw strikes. Most records are incidental, not a common gamefish.
