I know that generally bristle worms are good for reef systems or at least not all that harmful. However I was feeding my open brain coral this morning with my little led flashlight. At first all was good and checked back a few minutes later to see how it was making out. Noticed a really big long birstle worm, it had one end attached to a ledge about six inches above my brain and the other end sweeping across the sand heading towards the brain. The bristle worm must have been at least eight inches long. At what point should I think about trying to get him out?
