I just got a piece of this about a month ago. The guy at the LFS was so sure it was flowerpot but I didn't believe him. Eventually I looked it up and sure enough it was. Anyway, the frag of it that I got is about 2"x2" and took about 2.5 weeks to fully "expand", previous to that the polyps were firmly entrenched in the coral and were unwilling to come out. As well the tissue surrounding the polyps was a bit pale. Currently it looks pretty happy, polyps are fully expanded (as expanded as it gets I suppose) and its fully colored up.
Well this isn't exactly long term experience but thought I'd chime in anyways
