Coral Hawkfish (Cirrhitichthys oxycephalus)
Description:
The Coral Hawkfish is a hardy and charismatic reef fish, easily recognized by its reddish to pink body with darker mottling and its habit of “perching” on coral or rock ledges. Unlike many fish, it does not have a swim bladder, so it rests on surfaces, observing its surroundings like a hawk. Known for its personality, boldness, and ease of care, this species is a favorite among marine aquarists.
