   All,
   
   I noticed on one of my Goni frags that I have a small creature that looks like it captures food like a porcelain crab. Is there a worm that has the same tool for capturing food? If so is it best to try to get them out of the frag or are they harmless? Polyps around the area seem to be fine but thought I would ask,.

   Most likely a barnacle. I have some in a couple mariculture colony's. As far as I'm aware they aren't a problem.
