That appears to be a nudibranch of some kind, though I'm not sure what kind. I'd guess based on the body shape that it eats some kind of Cnidarian though (such as anemones, corals, etc.), so if you have any cnidarians in your tank, I'd check them for eggs/damage.

 

[Turkey head]

That looks similar to a type I had that ate soft corals.

Cerith eggs, mine constantly laying them on my glass. I think you got your answer about the nudibranch. Good luck.
