What kind of worm is this?

This isn’t the greatest video, but this stringy thing just crawled I to the shell. It was taking some sand with it. I’m not sure if it should stay or go, and what to do to get rid of them (assuming more) if necessary.

I just grabbed a screenshot of it and circled it. Not sure this is any better.

Looks like Medusa spaghetti worm. Good detritus feeder.

Will it hurt any corals? Do they tend to stay in the sand bed?

No, they tend to stay in the sand. Just make sure no corals are in its path as when it drags detritus back, it could irritate corals if it’s in its path.
