I have a pictus with Neons in a 55G, and he doesn't even bother them at all.
As long as you keep the pictus well fed, he shouldn't bother other fish, but they are very active swimmers, very very active. When my pictus was a "baby" he would actually eat algea, I think. the corner of the tank he stayed in was always algea-free. He gets very excited when you put food in, and since I keep him well fed he hasn't touched the neons, and he hasn't harmed my snails either. Although I suspect he has been eating some smaller ghost shrimp, either that or they are just hiding.
And yes, I can second the net thing! I moved my pictus with a net and he got stuck! I ended up cutting the net with sciccors to get him out, and he seems fine now, but was a little freaked out for about a day, but now he's excited to be in a 55G instead of a 10G!
