I found rearing them to be very easy, but had no luck with breeding!
I live in a desert, so I did mist them twice a day. But I think once a day would have been just fine. I also kept them at relatively low temperature 24-27C. Higher temps caused high nymph mortality in less then an hour!
My nymphs had no real molting issues. They also were very good feeders.
This isn't a fast growing species, and is fairly long lived. I am down to my last male and he has been an adult since mid- January.
I also kept them together in a 10 gallon tank. I kept them well fed and saw NO evidence of cannabalism.
