Help, ID this worm

The worm is circled in red. It is definitely nocturnal. Never seen it in the day, and it didn't like the flash at all. It was gone right after this pic. The pic is crappy, but its all I could muster without lights to focus. Maybe someone can tell what it is.

I have a Peanut worm in my tank. Pretty cool little guy. Harmless
