teeny tiny white worms on glass of tank??

[krypton74]

We have some kind of small white worms on the sides of the tank. any ideas as to what they might be? we have two clowns, one anemone and a few fan worms. we haven't introduced anything new for about 6 weeks now - except live rock about 4 weeks ago. i am wondering if they came in on that. are they a parasite and are they harmful? our tank has been set up now since february so our cycle is good to go for more species and we'd like to get a few more inverts, but i am concerned!
thanks all!

after doing some more research after posting (i know - i should have done more BEFORE posting), i went and looked real real close at those buggers!! they are spiral like someone mentioned on another thread and they are actual tube worms!! yes - they have the teeniest little wavy worms poking their heads out (can you stinkin' beleive it????) anyway, i thought i would post the results.
in the meantime, i have seen many posts about pods which i thought maybe that may haver been a possiblity, thank goodness it isn't the bad ones! boy - i will be watching for those little sh*%ts!!
