Worm (?) ID Request

[Xolsiion]

Below are two pictures of something that I've recently seen at night after the lights have been off for at least an hour or two. It has a segmented armor-like top, is about two inches long, and moves at about the same speed as a snail. I have also seen a thinner one about half this ones length. It also seems to mimic the color of the rock as its coloration isn't the same as the other time I saw it. You can also click either picture to get a really big picture with much more detail. Any help is appreciated.

It's a Chiton, from what I understand they're a good addition to a reef tank. -Steve

I doesn't look exactly like a Cirolanid Isopod, but if it is....they are a very tiny creature that feeds on fish similarly to ticks on dogs. Usually these appear affixed to the body of a fish, or gills. Do some research on how to remove them - they are unwelcome pests. If left unchecked in your tank, fish will die. You will need to leave your aquarium fish-less for 2 to 4 months to erradicate these.

I got this quote directly from Melevsreef. He's got a great identification page. If you want to check it out follow the link below.

OneArmedBandit could be right though. i would check it out anyway.

It's not an isopod, it's a chiton. Cheers,
