Tailspot Squirrelfish

Sargocentron caudimaculatum

Tailspot Squirrelfish (Sargocentron caudimaculatum) is a nocturnal reef fish with a dark spot near the tail and large eyes for low light. It shelters by day in caves and ledges and forages at night on small crustaceans and benthic invertebrates.

Identification points

Distinct dark tail spot on the caudal peduncle
Bright reddish-orange body with pale longitudinal lines
Very large eyes and a stout squirrelfish shape with spiny dorsal fin

Habitat

Coral and rocky reefs, reef slopes, and lagoon drop-offs; shelters in crevices, caves, and under ledges during the day, usually from shallow water to moderate reef depths.

Bait notes

Small strips of shrimp, squid, or cut fish can take it on light tackle; tiny jigs and small soft plastics worked near reef structure may also draw strikes at night.

Behavior

Mostly nocturnal and secretive by day. Feeds after dark on small shrimp, crabs, worms, and other bottom-dwelling invertebrates, often close to structure and reef relief.

Caution

Sharp gill covers and spines can nick hands when handling. As a reef-associated species, eating large individuals may carry some ciguatera risk depending on location; check local advisories.

Fishing notes

Fish after sunset around reef edges, caves, and drop-offs with very light leaders and small hooks. Keep baits close to structure and use a slow retrieve or dead-sticked presentation; it is not a major target game fish.
