Hello Tawnya:
I'm sure Jobi and FroggieB will be chomping at the bit to help you because they work with lots of Acanthosaura. I have a few of them and have worked with them off and on for many years but not to the extent they have.
Mine have been fairly easy to work with once they were established. The males will flare up a bit and defend their territory which is a good sign that their health is in a more stable condition. Even so, if I offer crickets slowly and not menacingly from my fingers they will feed from my hands. I keep mine in terrariums with some live plants and vertical perching spots for them to retire to at night. They are somewhat of a humidity loving group of lizards so a large water dish is not a bad idea. Mine spend at least a little time sitting in the water during the daylight hours. Your 40 gallon high should be fine for your Acanthosaur. Given a little time to adjust with a minimum of distractions these lizards make wonderful terrarium animals. All too often I think the demise of many of these lizards is overhandling and improper environmental conditions. Most will feed willingly with little to no provocation.
I'm sure the others will fill in a lot of the blanks. These are tropical lizards so the temps should stay in the mid eighties with a slight drop at night and a basking site that can get a tad warmer.
You should check out some of the threads in this forum. There is lots of usable info here and plenty of photographs of both animals and the housing they live in.
Good luck and feel free to post any questions you may have.
Have a Great Day!!!
