I think this is a peanut worm what do you guys think? I have had this tank up for almost 2 years now and this is the first time I have seen this worm.

It looks similar to the things I have in my tank that I have always called peanut worms. Not really sure why I call them that other than I've heard the name and they just remind me of what I think a peanut worm would look like. They graze on algae and detrius in my tank when the lights are out. They shoot back into themselves/holes when I shine a flashlight on them.
