Suicidal Nudibranch?

Just added a purple NB to my 46, and i had to pull him off the filter intake earlier, and he keeps making for it...he seems okay after being sucked against it, but is this behavior to be expected? Can I prevent it somehow? As I speak, he's nosing up against it again. Not sure how long he'll last next time...I did rearrange the rocks to try to distance him a little more, but between the glass and the rocks, he can get close. Ideas?

Well a few things come to mind. How old is the tank? If the tank is fairly new, maybe there isn't enough on the rocks and sand for it to eat. So it is heading for the filter, because there is probly more for it to eat there.
Have you read up on these at all. These are highly toxic and when they die, they can pollute your tank with a toxin that can kill everything in your tank. They also have a very strict diet. And if your tank hasn't matured enough they could starve to death.

Have read up on these, yes, but have gotten conflicting reports...the lfs, a lady I'v found (in the past) to be fairly knowledgeable, assured me that it would keep easily in the tank, and last quite a while. Today he's been mostly okay, last night kept away from the filter---my concern was more for when I saw him passing by the filter, and he's so light that he was sucked toward it...but he seemed more cautious near it today, and steered clear.
All that said, if I'm displaying a naivety here that I'm unaware of, please let me know, as lfs's are notorious for bad info.

In general, the best way to see if a LFS knows what they are talking about is to ask specific questions.
In this case, what is the species of Nudibranch? What does it feed on? If tehy can't answer either of those questions, steer clear.
