Hitchhiker ID - Aquatic Roly Poly?

[The Skeptical Reefer]

Anyone know what this hitchhiker is? It came in on a frag from a recent live sale.

It looks like a small aquatic version of a roly poly. It has a bunch of legs (10 at least?) and two very small distinguishable eyes.

it could be an amphipod

It looks to me like a chiton. Can you get a closer picture?

Isopod. Some are predatory but yours looks to lack the big and scary, evil eyes.

Isopod. Some are fish parasites. Nasty buggers if it’s a parasitic version, get rid of it.

Thanks for the quick responses everyone. Here's a few more (hopefully closer) pictures to verify. Any closer and my camera loses focus.

Can’t tell for sure if it is the good or bad kind, probably is safe (I’m not good at the differences).
Reason it looks like a roly poly is because it is. Roly poly are a type of isopod!
