What is this on my hammer frag?

What are these hard Spiral stalks coming off my hammer frag? They’re not movable and are very hard. Thanks.

Look like vermatid to me. They will reproduce and invade. A pair of pliers will crush the tubes and kill worms that live inside or you maybe able to scrape them off with a knife. If they are too close to the coral, a drop of super glue on the end if the tube will work .
