Looks like some kind of nudibranch. At first glance, I would have said polyclad flatworm, but the head formation looks like a nudi. No idea what species, there are a lot.
Definately a slug. I've run into these guys at work, but couldn't tell you what kind of coral they arrived with or what they were eating. And with so many similar looking nudibranchs, even if i could it wouldn't be of any use!
