just ordered 300 and 3 adult pairs so ill have 18 adult pairs to start off with from aaronpauling.com. and i ordered 2 ounces of water crystals because i hear these are easier to use. but i dont have any egg crates/flats so what could i use for them to hide in alternatively? and what is the best stuff to feed them? crushed up dog food? how do i keep the humidity up and should i use a heat pad for heating?
