I was talking about most pet stores, not all. I have found a few that have a genuine interest in the axolotls, and actually take the time to read up on them, and if they aren't sure about something, they ask questions.
Then you have some exotic pet stores that think they're right about anything, and if a guy with long hair and a bunch of lip rings goes in there and tells them them that spotted salamanders don't like heat lamps or dry sawdust, they look at him like he's the idiot! (trust me, I've been there!)
Pet stores are ok for buying products, but for newts and salamanders, it's best to make connections with breeders and/or collectors because generally you can learn the most from those people.
