little hair like worms?

[kcfehring]

I posted a question a few days back about these long thin white hair like things in my tank.

They look very much like a long (any where from 5mm to 2cm long) white hairs. They live in the sand substrate and in the rock. I think they are worms because you don't always see them...it's like they can retract. They blow in the current.

I thought that someone had posted a link to something that they looked like but when I tried to find it the post was gone and I can not figure out how to search. If you know what they are or a good place for me to look them up I would appreciate hearing from you. I would like to know if they are good or bad for my little reef and what, if anything, I should do about them.

Thanks,
Kim

Probably harmless Spionid Worms. Here's a great id page - http://home2.pacific.net.ph/~sweetyummy42/hitchhikers.html
