i have a few in my tank they mush have hitch hiked them way in,
i would like to know what they are so to know if they are good or bad and what the need
+1 I had them really bad when I first started my reef tank they ate damn near all my zoa. I'd defiantly get that bugger out ASAP. Your corals will love you for it.

I cant tell what kind it is but is does look like some form of nudibranch. the colors kind of say sea hair to me but I would not chance it. because it could be something you could regret later. Your best bet would be to remove it and keep an eye out for more. when you remove it you always could take it to your lfs for an ID or post a closer photo here and we could ID it proper if you wanted to. But again I would not want to chance it. most nudibranch are tank villains and best to be removed than to wait and see what happens.
