The way I've always learned the most about something, especially in business, is to go out of state, to someone very knowledgable that won't feel you're a threat to their local business, and hang out and watch and learn from them.
Best experience for learning tricks someone won't publish or are currently experimenting with, at least by my experience.
If you go hang out with the great breeders you also get to see what their climate is like, and how they deal with their particular weather, humidity, diseases inflicted due to their climate and such.
We don't have much humidity in AZ, and most other places in the US do, so how you handle a situation may not be proper for here.
These programs on discovery and pbs and stuff are awfully entertaining though
When I was into fish, african ciclids, I would visit one of the best breeders in the country, and he'd tell me stuff that I'd not heard before.
Simple things like if a fish, maybe most 'animals' have something to take possession of, they get a reason to be aggresive, so don't give them anything to fight over. Don't know if this applies to mantis' psychology though.
Also, he said the more fish you put in a tank, the less aggressive they get, and start to adapt and get along with each other, so he said. I don't think mantis' are the same, but time will show me it it's so or not. I would imagine that this could be species specific.
