Chocolate Grouper

Cephalopholis boenak

The chocolate grouper is a Indo-Pacific reef grouper that lives on coral and rocky reefs, often near drop-offs and ledges. It is a compact ambush predator that takes small fish and crustaceans and is usually caught incidentally rather than targeted in most areas.

Identification points

Dark chocolate-brown overall coloration with a compact grouper body
Pale bluish spots or speckling often visible on the body and fins
Rounded tail and a relatively large mouth typical of small reef groupers

Habitat

Coral and rocky reefs, reef slopes, lagoon margins, and drop-offs in the Indo-Pacific, typically sheltering in caves, crevices, and under coral heads from shallow water to moderate depths.

Bait notes

Small live fish, squid strips, cut bait, and shrimp work well. Small jigs and soft plastics worked tight to reef structure can also draw strikes.

Behavior

A sit-and-wait predator that ambushes prey from cover, feeding mainly on small fishes and crustaceans. It is generally solitary and more active around structure and low-light periods.

Caution

Spines and gill covers can cut, and reef fish from its range may carry ciguatera risk depending on location and size. Check local regulations before keeping any grouper.

Fishing notes

Fish close to reef edges, holes, and ledges with stout tackle and short leaders to keep fish out of cover. Slow retrieves and precise bait placement are more effective than long casts.
