I've just got a few of these the other day, not kept them for about six years now so I jumped at the chance when I saw them. I found they were quite easy to keep regarding temperature and humidity, room temp was fine and I sprayed them every third day, I definately wouldn't keep them together as they are ravenous and eat almost anything even if its bigger than them, I didn't like using crickets for them as they seemed to make them sick and a couple of them died, never had any problem with flies or moths.
