Tiny thread like worms

[Blackweb]

Could anyone ID these thread like worms? They have a white body with an almost cream colored head. I have a couple pictures and i can get more if needed.

Looking at the bulbous head is that some sort of Eunice Worm?

Not sure exactly but for a size comparison, here they are next to ricordea. I could also gather that when disturbed, they very very quickly recoil back into the rock.
