Isopod ID

[Rwade]

I’ve been seeing a few of these isopods in my filter socks lately and I can’t positively ID them. They look like Cirolanids but the eyes are further apart. They are really fast and I haven’t poked any of them to see if they can roll up in a ball. They have not caused any problems (yet) and I’m not sure how I would go about eradicating them anyway. If we have any isopod experts, I would appreciate a positive ID.

I have some fish that would love to eat them.

Your fish would need night vision googles. I only see them after lights out or in the filter sock.
