Beardies as babies will eat a lot, 50-75 or even 100 crickets a day, crickets or roaches shouldnt be any larger than the space between their eyes. As adults they need about 6sqft of floor space. Low humidty. DO NOT USE SAND. I breed my own roaches and worms so my feeder cost is $0. They require UVB light.
