very small clear worms?

[Necsones]

today i was just looking at everything im my tank, watching my hermits and snails and then i came accross these very very very small clear worms. They are crawling over the rock and some crawl into the rock. are these bad? i tried to get a pic but camera cant zoom in that close. will try to get pics soon with another cam.

Ive had these too, they seem to grow in population then die off, pretty sure thay are harmless. how old is your tank? pics would help - Ive had good luck putting the camera up to a jewelers loupe (get one on ebay for $5)

you can get good blow ups like that -

They could be a small species such as the Dorvilleidae or the juveniles of any number of polychaete worms.

They could be a juvie bristle worm. The purplish/pink color makes me think they may be fire worms similar to the one I have in my tank. Not a problem so long as you don't touch it.
