Ya no problem, I have a 20 gallon long critter cage, made by all-glass. The dimensions are 30 x 12 x 12 inches. The tank has an under tank heater to one side (to make a hot and cold side), with hides on both sides. I have a water dish in the middle with a piece of drift wood along the back. Also just to boost my daytime temps I have a heat lamp with a infra red bulb over the hot side. Currently I'm using playground sand as a substrate, but I recently aquired some calci-sand which I'm contemplating putting it in. Also for feeding mealworms I use a little dish which is shallow enough for the lizards to reach in and eat, but deep enough to stop the mealworms from escaping. I also feed them crickets, and really there's no way to harness them from what i can tell. I'm not too fond of the playground sand because it makes them a little dusty and I'm scared of impaction. Hopefully that helps. Oh yah, and the daytime temps can reach up to 105 in my tank. If the tank gets too hot, I simply put more sand on the hot side and the UTH cant heat it up as much (vice versa).
