As with most tanks you need A warm end and A cool end. So as I do put the bulb on an end or middle and than build A basking point under the bulb. Stair step it so the lizard can kick back and relax at the temperature range it is seeking. ALWAYS provide A cool down area. So when you get your little guy you will see them under the light with their mouth open. They do this because they are to warm but they know how full their tummy is and without the heart they cannot digest properly so they let the heat on their belly and cool down the head by open mouth breathing.
Another little trick. When you get the little one they tend to gulp their food. Actually they all do but the babies over does it. This is not good when eating worms and crickets as they need to be crunched up so as not to bite the inner parts. Best way I found to avoid the problem is feed some greens first. That way they are not so hungry and they will dine on the worms instead of gulping them whole.
