I am more afraid that it's one of these...Eunice worm



They seem to share the same mouth...multiple tentacles at it's entrance.

If it is a eunicid worm, then it could be good or bad. I had one for a long time that was vegetarian. I probably have several hundred in my tank right now, but they are all small and harmless.
