I just fed one of those to my P. regalis yesterday.
As far as general care and breeding, it's pretty easy. MH are tropical roaches so they like it warm and humid. If it gets too cool or dry they tend to not breed as well. I keep my box pretty warm, generally about 80+ degrees and I keep the humidity around 80% (mist real good every day and keep the dish of water crystals full).
They do like to burrow/hide so you can either provide enough substrate for them to burrow in or put a bunch of toilet paper rolls in there for them to hang out in and some clean egg cartons work good too.
Oh, and remember, they'll eat just about anything. They are especially partial to peanut butter and jelly sandwhiches and over ripe bananas.
