Hi. I got this Beach Bum montipora a couple weeks ago and thought these two dark marks were damaged polyps. But now I think they are something different altogether. You will see that one of them has a streamer thing coming out of it. Are these vermetid snails punching through the coral? Or are they on top? If so, how would you deal with this? I do not have vermetid snails in the tank.. or I didn't. If they are not vermetid snails, can you assist with other ID? Thank you everyone!
