Hair like worm on GSP???

[hexcolor reef]

Hair like work on GSP, it moves in and out of the coral. Doesn’t seem to bother it but I prefer a clean tank.
Would a dip take care of this or hydrogen peroxide dip? Does anyone know what this is?
harmful or not?

Are you only seeing them after lights out?
