I keep mine on the top of one of my snake racks where it's quite warm and they do well there, I feed them nothing but veggies (kitchen scraps) they go nuts for oranges, they don't seem to care all that much for grain products (breads crackers etc) . They would not breed for me at typical room temps. One thing to remember is do NOT feed off your breeders. People assume that they 'breed like roaches' but in actuality these are tropical roaches and not your typical pest species. It can take 6 months or more (depending on temps) for them to reach sexual maturity. I've known several people who have crashed their colonies by feeding off the biggest ones to their monitors or dragons. (actually you can feed off the males, you really don't need that many, but leave the breeding size females alone)
