It has eyes

This thing was on my clown several weeks ago for about 2 days but then it was gone. I figured the anemone ate it off the clown because of their close relationship. The picture is my magnificent fox face’s tail. He wasn’t on him yesterday. Is this a concern? Thanks for your help

Predatory Cirolanid isopod, not great to have. Not terribly harmful by itself, but they are bloodsuckers and a large infestation can potentially make fish anemic.

Here's an article on how to trap these buggers.

Agreed with the above - a parasitic isopod species. You definitely want to get that out.

Thanks for the article. It’s very thorough.

The foxface has kicked the bloodsucker. Now I need to make a trap and do some hunting.
