mystery critter

[k8y]

I found a weird creature in my 55 gal FOWLR. At first i thought it was a feather duster but i noticed it crawling along like a worm and changing shape. It is the color of a feather dusters tube but looks more like an earthworm. I caught it in the net and it shrunk up and now looks like a fat elbow noodle. One end is fatter and has a nipplelike protrustion and the other end is skinnier and has a hole... any ideas what this could be some kind of worm maybe?

Picture would be nice and needed for proper ID...

could be a sipunculid, aka peanut worm
