Longspine Squirrelfish
Holocentrus rufus
Longspine Squirrelfish is a nocturnal reef fish from the western Atlantic, common around coral and rocky reefs. Its oversized eyes, red body, and very long rear dorsal spine make it easy to recognize; it is mostly of interest to reef anglers and divers rather than as a target species.
Identification points
- Deep red to orange-red body with paler belly
- Extremely large eyes adapted for night feeding
- Very long last dorsal-fin spine extending well behind the fin
Habitat
Shallow to moderately deep coral and rocky reefs, reef ledges, caves, and crevices; often shelters by day in dark holes and emerges at night to feed.
Bait notes
Small pieces of shrimp, squid, cut fish, or crab work well; tiny jigs tipped with bait can also draw strikes. It is rarely a primary gamefish target.
Behavior
Primarily nocturnal and crepuscular, feeding on crustaceans and small benthic prey. By day it hides in reef structure and may form small aggregations in sheltered spots.
Caution
Sharp dorsal spines can inflict a painful puncture; handle with care. Not considered a major food fish, and local reef-fish consumption advisories should be checked before eating.
Fishing notes
Fish after dusk near reef edges, holes, and ledges; present bait close to structure and keep tackle light but sturdy enough to pull fish from cover. Slow bottom presentations are usually most effective.
