I first noticed this large worm during a red-light check of my tank a couple of hours after the lights turned off the other night. I've not seen it before. The exposed body was about three inches long, and it's about 1/4 to 3/8 inch in diameter.

When I turned the room lights on, it withdrew into a hole in the LR. Can anyone help ID this worm for me? Is it a good guy or a bad guy?

It's a chiton in the genus Cryptoplax. Beneficial cleaner.

Thanks, LeslieH! I found photos on Google based on your ID, and that's it. From what I've read, it seems to be a large specimen.

I'm always amazed at the new critters that show up after months in the tank.

yea I can tell by your pic that its the same kind.
as you can see from my post there that I've been seeing mine for quite a long time.
when I was googling it some article said they can live up to 20 years.
