Critter id ?

[Scottland]

Looking to id this Critter. It's tiny, I zoomed in with 8x. It seem to have long sweeper tentacles. Aiptaisa maybe?
Thanks,
Scott

Hair worms belong to the family Cirratulidae while spaghetti worms belong to the family Terebellidae. I never tried to figure out what differentiates the two since both are beneficial scavengers/detritivores.
