Yellow Nudibranch hitchhiker

[Wilsoni]

Just discovered this little guy hanging out near the waterline of my aquarium. Is it reef safe? Should I pull him out?

I know there are tons of species of Nudibranchs with little known information and they can become quite difficult to identify but any information on it would be greatly appreciated. (:

What new coral or plant have you introduced to the system? Looks like the kind that comes in on Chaeto or Caulerpa, I'll have to look it up.

I recently added some SPS frags but I feel as if I would have noticed it upon my initial inspection. Thanks in advance!

It appears to be Elysia the "Caulerpa Slug." Thanks for the link. (:
