Fast White worm thing

[Mflores888]

I found this thing near some of my rocks. I have no idea what it is. So far I've looked around and haven't found others like it, but it's pretty fast moving. When I pulled it out I accidentally cut it in half and this morning the other half has started to move around. My first thought was flatworms but I haven't introduced anything in some time.
