Nudibranch ID Help

[Majority_Rules]

Help ID this, please. From a Google Images search, I'm thinking it's one of the ones that eats zoas. The (LARGE!) pictures are in the links bellow. It's hard to tell in the pics, but his body is purple-gray and the appendages hanging off his back are green-yellow. I just want to make sure he's up to no good before I give him the boot.

Looks a lot like this one. He's actually really pretty.

Those are aeolid nudibranchs. Predatory. http://reefkeeping.com/issues/2005-05/rs/index.php
