What is this

Saw this on my new leather coral and am unsure what it is.

Sorry I've never seen this before. At first it looks like algae stuck to it but when you zoom in it looks like it coming out of the coral. @Tahoe61 have you seen this?

I would attempt to remove it. Can't really tell from the photo, but my first guess is a nudibranch.

I pulled it out and it was a lot longer then I thought.
