Threadfin Hawkfish
Cirrhitichthys aprinus
Threadfin hawkfish is a small reef perch found on shallow coral and rocky reefs across the Indo-Pacific. It perches on coral heads and branches, darting to snatch tiny crustaceans and other passing prey.

Identification points
- Long thread-like first dorsal spine filament extending above the fin
- Slender hawkfish body with mottled brown to reddish camouflage
- Dark spotting/barring on fins with a perched, upright posture
Habitat
Shallow coral reefs, reef slopes, lagoon patch reefs, and rubble areas with branching corals or sponge/rock perch sites; typically in clear tropical saltwater.
Bait notes
Not a common target species. If taken while micro-jigging or on small reef tackle, tiny pieces of shrimp, squid strips, or very small soft plastics may tempt it.
Behavior
A sedentary perch-predator that sits exposed on coral, then makes short lunges at zooplankton, small crustaceans, and tiny fishes; often retreats to the same perch when disturbed.
Caution
Handle carefully around coral to avoid cuts; the species is small and not generally valued as food. Follow local reef-fishing and coral-protection rules.
Fishing notes
Best caught incidentally with light reef gear; use small hooks, minimal weight, and present bait close to coral perches. Avoid damaging live coral and release promptly if not keeping.
