Any idea on what this guy is?

I've seen this a few times now. At first I didn't think it was anything but part of the rocks, since it didn't seem to move. Now I've seen it move locations.

Seems to have small 'legs' on the sides, segmented body? About the size of a grain of rice. Here are two pictures to help

Looks like a chiton. Good guys to have.

Thanks! After posting I thought that might be what it was. No telling where it came from, but glad to have another neat tank mate!

Not sure if you knew this but I see some vermitids on the first picture. The other little guy is a chiton.
