slinky worm attached to glass and rock

[CamaroZ28]

Hi,

I have not added anything to my tank in the past few months, but yesterday I noticed a new critter. It looks like a worm of some kind. There was one on my glass, and another in one of my rocks. The one on my glass is about 2 1/2 to 3" long, and looks like snail slime almost, but is bright white, and very thin and lacey. The worm is shaped like multiple loops throughout its length. If it was to be extended it would probably be about 5 times it's length on the glass. I know I really need a picture, but could someone help identify it until I can take one?

 

Thanks,

-David-
