Some nudibranchs are reef-safe, other are not. Most have very specialized diets that may be "impossible" to replicate in our closed systems. Some have toxins in their tissues that can damage your tank when(if) they die. Most nudibranchs aren't suitable for closed systems at all. Having said that, I've heard of and seen "Algae Eating Nudibranchs" as well as Lettuce Nudis which in this case were different looking specimens. Some people have success with Lettuce Nudis, but I don't know much about the ones I saw that were simply labelled "Algae Eating Nudibranchs" (and weren't Lettuce).

Either way, many snails eat diatoms. Try a couple Astraea snails. :)

P's really don't care what there customer's tell them about there stock. They think they know it all when it come's to all livestock & IMO they really don't. Any time I have stopped there to get bone's & goodies for my Huskies I take a look around & have never been asked if I could be helped with something or what have you. Not a fan of the customer service there.

Isn't this one o those that if they die and you don't get them out right away it will bomb your whole system?

well it dissapeared and i never took anything out. everything was fine but there is always the chance it climbed out.

It's a species of phyllidiella nudibranch. They are extremely toxic. And yes they can possibly nuke your tank.
