Pacman frogs are great, I got my first one around August of 2014 and I like to introduce him to people as "my son".
He's really not nearly as aggressive as I expected. He's made me bleed a couple of times while feeding him, that's about it though. I don't pick him up often to begin with, but when I do he's usually really chill about it.
My only frustration is that I've only ever been able to get him to eat nightcrawlers. They say to feed them a varied diet, but if I offer crickets or whatever he won't have anything to do with them.
