Any idea what type of worm this is?

Apologies for the crummy picture. I have this guy growing in my tank for the last couple months and up until recently I just assumed it was a Spirorbid worm but it's much larger than any I've seen before (about the size of a dime). Just wondering if anyone can ID and if I should be concerned about it bothering corals?

Side note: While I don't actively encourage hitchhikers, I typically don't mind unless it's causing issues.

That's the biggest one I've seen which is probably why I didn't make the connection. My previous tank had tons of little tiny ones.
