This looks like a star coral, but the color is weird. There were many of these "blue corals", especially to the south of St George.
Are bluish corals results of bleaching?

My understanding is that the blue coloration is a last ditch effort by the coral to protect itself when the algae is gone due to bleaching. I dove six weeks in Bonaire recently and watched many change from blue to green again as the waters cooled.

That looks like Siderastrea siderea. They usually turn a purplish blue when they bleach.
