David I have found live C. granulatus in in Honduras. I concur with Wayne's light assessment. During times of bright moons and no cloud cover they were almost nowhere to be found. Leslie David, I have found live C. granulatus in the Grenadines -- but never in the daytime. They are very shy about daylight and even bright moonlight. They are usually associated with dead areas of reef structures where they feed on the shiny black coral boring worms. Wayne Harland [log in to unmask]
