Didn't know you wanted an ID on that, I could've told ya. Pearl bubbles are one of my favorites. Kind of finicky though.

Finicky eh... hmm everything I read say they were a beginner coral. What problems have you encountered so I know what to look for?

I like my pearl also.
Here's an older pic.

It's doing really well so I don't know what Wax means about finicky

maybe something with light and water movement or it's sweeper tentacles. Mine doesn't seem to mind the CFs and now the halides. It really swells up. I may get a small green one later.

You have to be careful about current, they like it low. They also react quickly when water parameters are off. Mine ended up dying for no reason I could ever fathom after about 8 months.
