Small white worms?

Hey everyone. It's been awhile since I've posted any inquires, mostly because you all have helped me have a perfect tank.

Anyway, I've noticed (usually in the late evening) a few little (and I mean tiny!) white worms swimming around in the flow. When they swim, they have a "corkscrew" motion.

I tried to take a pic, but it just looks like dust on the lens... They're kind of quick little buggers, too!

Any ideas?

 

Maybe parasitic worms? What and when was the last thing added to your tank? Maybe they were hitchhikers that were dormant for a long time.

 

Last thing in was my Yellow Tang....about 6 months ago. Nothing seems to be affected by them.

Also when the worms are swimming, they tend to veer away from the fish.

 

Could be juvenile bristleworms.
