Why? Bristle worms are a normal part of a healthy system. They are part of the cleanup crew and eat all the unmentionables in the tank. The won't eat anything that isn't dead or dying.

+1 to it being a good addition to your clean up crew. It is nothing more than a bristle worm. Yes, they can become very large - I have at least one in my refugium that is atleast 8 or 10 inches long. It is really cool to watch it eat.
