Little 1/2” long worm

This little guy showed up when the blue lights came on. Cruised around on the glass then disappeared into the sand. That’s the best photo I could get. No obvious head / legs / identifying marks. Just a little white worm. Any idea?

Have you seen it again?

The only time I have seen it was last night after the blues came on. I think it might be some sort of detritus worm but I’m not sure.
