They eat fruit stuffs. Apples, pears, any kind of decaying vegetation. They're surprisingly low maintenance. Makes me really excited to own some someday. And apparently they don't eat for the first few months that they're adults.I'd never really thought about it before. That might be interesting. What would you feed them? I've tried keeping a praying mantis before but when it wouldn't eat the bugs I'd catch and throw in with it, I let it go rather than let it die. People keep pet tarantulas and pet snakes. I don't see how this would be any different.
