We are new at having LPS/SPS coral in our tank and have a question about the growth of stonies. On several of our recent additions (from the Frag meeting!) a small semi-clear sack/bubble has appeared at the tips. This is especially true on the montipora digitata. Is this growth? I am trying to take pictures but our camera s*cks. All the corals seem to be happy. No die-off of the flesh, polyps out, and the colors look good so I am hoping this is growth.
