What is this?

So recently, I spotted this fuzzy red egg like appearance on my feather duster worm. I have no idea what it is or could be. Let me know please! I attached pictures. I tried scraping one off, but it didn't. It's like it's stuck to it? My other worms don't have that stuff stuck to it. So could it be a parasite? Worm mating? Fish eggs? Shrimp egg? It doesn't look like aptasia. And the deeper you get into the ship, where the back of the worm is, the more there are.
