When I took my 75 gal. reef down due to a leak(new tank being setup) I was able to get this picture of a worm I had only seen from below the tank. Is this a harmless type of Bristle worm. Must have been in my tank from the begining, never bothered anything. I just don't want to put it back in my tank if it is bad.
