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.
