Help needed to identify.

No sure what this is on my foxface. It seems to be new and doesn't seem to affect his swimming, behavior or eating. Should I be concerned?

It could be a bite from another fish. If it appears to be a creature then probably Cirolanid isopod. Can you get a closer pic?

Could be a nip from a fellow tankmate. I would observe for now and see if it improves or gets worse.

That's what I was thinking. I know he is skidish so possible he got startled and injured himself.
