Yet another alien from my new gsp

[FunWithFishes]

So I found another pest anemone come from my new gsp, that is being dealt with, however, there is another stranger hitchhiker that I have absolutely no idea about. Anyone have any idea what this fellow is?

Alrighty, thanks! From what I read these seem like good things to have so I will let him be.
