What is this creature in the centre

IN THE CENTRE OF THIS VIDEO, you can spot a white line moving around.

One of my shrimp just gave birth today. I noticed a full molt that had a few eggs attached to it(I’m assuming they were infertile/bad). Anyways, as I was filming the babies, i noticed a worm-like white organism on my screen. It’s so tiny. In the center of the video you can see a white line turning around a piece of aquasoil.
