Identification points

Deep red to orange-red body with pale horizontal stripes
Very large eye adapted for ночurnal activity
Long, sharp preopercular spines on the cheek/gill-cover area

Habitat

Steep coral and rocky reef slopes, outer reef drop-offs, caves, ledges, and deep crevices; usually sheltering by day in shaded holes and foraging at night from shallow reefs to deeper offshore reefs.

Bait notes

Takes small fish strips, squid, shrimp, and cut bait fished near reef holes; small jigs or glowing/bright lures worked slowly at night can also draw strikes.

Behavior

Primarily nocturnal and solitary or loosely grouped; rests in dark refuges during daylight and emerges after dusk to pick crustaceans and small fishes off the reef, often holding close to structure.

Caution

Handle carefully: the gill cover/preopercular spines are sharp and can puncture skin. As a reef predator, it may carry ciguatera risk in some tropical areas; check local advisories before eating.

Fishing notes

Fish after dark around reef edges, caves, and overhangs with light tackle and a quiet presentation; let bait sink close to structure and be ready for quick runs into cover. Usually not a targeted game fish.
