I've found (and read) that 85*f to 90*F is an great temp range for them. It's the best for breeding and appetite stimulation. Now that we've got a healthy colony established, I brought the temps down to between 70*F and 80*F, just to curb the breeding a bit until we need to build them up again (we've only got two beardies). I use a dark Rubbermade bin to house them, with a screened "window" cut into the top of the lid for a bit of ventilation. For heat, I have the bin sitting on a "human" heating pad, with a ceramic heat emitter hanging over the screened window for the Winter time if needed. As far as what I feed them, I keep one bowl filled with a specialized roach chow and dry, organic puppy chow, and another with water crystals, both available at all times. Then I have a third dish that I use for all of the "fresh" foods; dark leafy greens, carrots, sweet fruits like mangos, papayas and bananas, oranges (oranges really seem to stimulate breeding), organic wet puppy food, human baby food, fish flakes, and even the Nature Zone beardie bites (our colony goes nuts for them). Every day or few, I spray water into the bin as well, to keep the humidity up.
It's sad, I take better care of our roaches than I do myself. :roll:
