ID this nudibranch please!!

Found this fella in my tank last night. I asked my friend and he said it eats snails and is a predator? Can anyone give me an ID please? Here is a picture.

Not a nudibranch - try googling polyclad flatworm. I think they eat molluscs, which would include snails and maybe clams. If you've got one, you probably have more, so keep an eye out.

I don't remember the name. Maybe the one mentioned above. But I do know it's bad and you should get rid of it.

Yep, polyclad flatworm. Predatory...snails, clams.
