Hmm, had to look up what the common names would be. From what I've seen, Sansibia is often called "blue clove polyps" or something to that effect, but clove polyps in general is probably "safer." Duncanopsammia aka "Duncan" or whisker coral. "Duncan" I have heard, but not the others. I know most of the scientific names and only a handful of common ones. No wonder people look at me like I'm crazy at work... I didn't realize I was that bad.
