Got some new live rock from Vanuatu and found these on the glass.

My camera is old, so this is the best I could do for a pic.

They are approximately 1/16 of an inch long. Kind of worm like. They hang on the glass by one end and sort of float their bodies away from the glass. What are they?

Wrong phylum. They are tiny snails in the family Caecidae. Here's some pics of a Caecum species from Europe --

And just for fun, here's a good blog post about the related genus Fartulum http://coo.fieldofscience.com/2009/05/stop-giggling-taxon-of-week-fartulum.html

These tiny snails are very abundant. I can remember cursing a lot as I picked hundreds of them out of my samples in the Caribbean. They're detritivores & harmless.
