Lighting- this is kinda controversial, but i believe that it is important to have a uvb bulb. i mean it can hurt. so you need a UVB bulb for uros.
Basking- Basking site has to reach 120-130 degrees, this is quite easy to do if you put a slate rock right under your basking bulb. i use a 150 watt and a 100 watt. But my cage is extremly well ventilated thats why i have to use two. i will probably take away the 100 once we turn on the heat.
Temps- 95-100 warm side 80 ish cool side
Food- I keep mine on a staple diet of dandelion greens and bok choy. then i give some watercress, kale, collard greens, turnip greens sometimes. Also i give wax worms every two weeks, about 3-6 per lizard.
Cage size- 40 gallon breeder(basically a 50 gallon) or more,the more floor space they have the better. i would say at least 3x2 feet is ok.
Substrate-adults it is ok to use sand. young uros paper towels of repti carpet.
Tame- not all uros are tame since 90% are WC. if you want a tame one get a CB mali, they are the most hardy and least expensive, since they are CB readily now. you should read the post below on "how tame is a uro"
Good luck and welcome
