Worm ID help

Got a new frag yesterday and decided to not dip it. This morning copepods are running rampant & there are some noticeably different creatures on the glass.. are these white planaria? Best option for population control to get ahead before they are an issue?

Can be Dorvilleidae worm which is a cousin of bristleworm. Google it and see if results matches or not. Still I am not sure see if anyone can tell better
