Also referred to by some as St. Thomas Ricordea. They were very hard to come by years ago, I see them more often now, you just have to hunt for them. Some have nodules and some are forked as in the picture above. I once had a colony of 30 on a football size rock years ago. They grew like crazy to the point I had to sell most of them off just to allow the rest of the reef to receive light. My favorites are the blood reds with white caps and the kiwi colored lime greens.
