Extremely slow moving. I saw it before, but couldn't get a picture of it. Not having any type of luck id'ing.

I'm pretty sure it's a chiton. A good hitchhiker.

It's hard to get a better picture, but it does not appear to have segments

I used to get the same ones in my big tank. They never seemed to hurt anything. Keep an eye on him.
