Worm ID? Maybe duster in Favia?

I just can’t tell if maybe I should try ridding them if they’ll populate and bother other coral? But it’s already been in my system. This coral already had coral rx, peroxide due to algae, and iodine before I noticed. I saw a hole in one of the ridges before and assumed it was a mouth forming.

Just leave it, or an issue for the tank? I read they’re similar to duster filter feeders but I don’t see how having it inside your coral flesh is great.

I have never tried to remove one.
