Not sure what this burrower is

Hey I found this little guy in a tunnel against the glass. Not sure what it is? It is about 1/4 inch or smaller long. Also by the looks of it kind of transparent. It does tend to move around in the tunnel. Here is a pic sorry if quality isn't so good had to zoom quite a bit. I added a 2nd better pic

I seen a better view of it and it defiantly looks like a white worm of some sort. You can only see part of it in the photo
