I noticed this 'thing' at the base of one of my corals. It appears to be some sort of feather duster or tube worm.

After a quick search it seems the best method to defeat these is to glue the tube shut. I found a few other remedies but the glue seemed the easiest. Then after a while I can scrape the tubes off so I don't have to think of them again.
