I think I have your same mystery. I will look forward to some input.

I had one of those. Now I have about 20. I'm looking forward to reading more on these things too.

The tube part kinda sounds like a feather duster. I've have seen some of my feathers moving around inside their almost transparent tubes, but I don't know about the web things. Could you maybe give a little bit more detail about this?

its mroe than likely either a ball of yarn bristle worm (Timarete filligera) or a spaghetti worm. (Eupolymnia sp.) both are really cool, and are very common in the marine aquaria!
good luck
