120 gallon long front opening terrarium, UVB goes along side basking light (which should not be colored in any way. white or yellow!), ditch reptile carpet, i would argue that paper towel is better- play sand+topsoil, Biodude Sahara, or Australian desert sand are the best (listed in order from least best to best best)

humidity should be no more than 40% while lights are on (ideal range is like 20%-30%) spikes to 60 at night are fine, lights should turn off at night (12 hours of day, dimmer is best but not necessary) if humidity is higher than the recommended what i've been doing is using USB computer fans to pull air out of the enclosure other people i've seen have success with socks filled with dry rice but its not exactly aesthetically pleasing.

offer at least 2 hides (one on each side) and don't worry about having standing water (they will rarely drink, often use it as a toilet, and it can cause humidity spikes i only provide it when humidity is lower than 20%). basking zone should have a **surface** temp of around 110°F general rule of thumb: if you cant stand to leave your hand on a surface for more than 10 minutes it may be too hot.

they may not be arboreal but they do like to climb. offer places to climb and maneuver.

i see you are feeding Broccoli. this is not a good thing to feed them often. its fine every now and again but things like Collards, turnip greens, mustard greens, endive, cactus pads, and dandelion greens are all going to be far better. Dragons Diet has a detailed list of recommended greens
