How To Identify It
Pale body with two orange-brown bands running the length of the fish, broken into blotches, and a dark spot at the base of the tail. Slender, with a straight-edged tail.
Where You Will See It In Cozumel
Over sand and rubble at the base of reef structure, often at the transition between reef and sand. More common below 15 metres.
Reliable sites: Paradise Reef, Chankanaab, Yucab, Tormentos, Paso del Cedral.
Behaviour
Hovers a short distance off the bottom and drops onto small fish and crustaceans. Like other Serranus sea basses it is a simultaneous hermaphrodite — each fish carries both male and female tissue and pairs take turns during spawning.
Commonly Confused With

- Tattler — Similar body, darker bars, and usually deeper.
