Crown Squirrelfish

Found in schools during the day, in crevices and under ledges, dispersing at night hunting for food, over open sandy areas of lagoons and seaward reefs. Dorsal fin looks almost black with natural light, in deep water.

Squirrelfish are nocturnal hunters feeding near the bottom on small fish and swimming crustaceans. During the day they often congregate close to reefs and in caves, sometimes found upside down in caves.
Their colour can change greatly in different lights and if threatened.
Some of this family have venomous spines.
