I have noticed a few holes appearing in my Aussie Goniastrea, and thought it was gall crabs. However, tonight I noticed a small black worm, with gold rings. It was quite dark, so no way to get a picture. Tried to grab it with tweezers but he slipped back into the coral. So, I have taken the coral out and put it in a qt tank. The worm does not appear to leave the coral. It appears to be borrowing in it. Any ideas what it is or how to remove it? I thought I saw it open it's mouth and the Unice (I think, or Euclid, I get these confused) telltale crown appeared, but it's late, not 100% sure. Is there a black and gold Unice that burrows in corals? Anything I can do to save the coral? Any dips work on them, or something? Wasn't a cheap coral... why do they always go for the good ones?
