Squirrelfish
Holocentrus adscensionis
The squirrelfish (Holocentrus adscensionis) is a nocturnal reef fish from the western Atlantic and Caribbean. It hides by day in caves and crevices, then feeds at night on small crustaceans and fishes.
Identification points
- Deep red to orange-red body with a silvery sheen
- Very large eyes adapted for nocturnal feeding
- Broad spiny gill cover and a single dorsal fin with strong front spines
Habitat
Coral reefs, rocky ledges, and sheltered crevices in shallow to moderate tropical Atlantic waters; most often under overhangs, in caves, and along reef drop-offs.
Bait notes
Small pieces of shrimp, squid, or cut fish work best; tiny jigs and small glow or shrimp-pattern lures can also tempt them at night.
Behavior
Primarily nocturnal and secretive, sheltering in groups during daylight and foraging after dark on shrimp, crabs, and small fishes; large eye size reflects its night-feeding habit.
Caution
Sharp preopercular spines can prick handlers; use care when unhooking. In some areas reef fish larger than this species may be subject to local ciguatera risk, but squirrelfish are generally small and not a common concern.
Fishing notes
Fish around reef holes, ledges, and structure after dark with light tackle and short casts; present bait close to the bottom and use subtle retrieves. They are usually a light-tackle bycatch rather than a primary target.
