There are a lot of coral show off threads, but none for Caulastrea. I am not surprised as I feel this is an underrated coral. As I approach filling my tank, I plan this to be one of the first species added. So fellow reefers, please show them off, curvata, echinulata, furcata, whatever you have. I would especially enjoy seeing colonies and different colored specimens together.
EDIT: Of course, these are also known as Trumpet and Candy Cane corals.
