Midnight swimmers

[gettowinch]

I'm sorry I don't have a picture. The other night I noticed that my 180 gal. had a bunch of very small worm like critters swimming toward the area where the light was. They look something like a bristle worm but no were near the size. Are these good, bad. If anybody can tell me where to look up about them that would be great.
Thanks,
Cat

Welcome to AquariumAdvice.com

They sound like epitokes, bristleworm larvae. If so they are completely harmless and nothing to worry about.

Cheers

Thanks Steve. I will keep a eye on them. I haven't had a chance to check them out this last couple of nights.
