Hi, I'm just wondering, if I were to get a Blue/Green Tree Monitor, what kind of cages would I need? (Examples of store bough cages and such)

Also, what kind of heating would I need? I know a light source of some sort would be needed, but do they need heat tape on the bottom of the cage to provide extra heat? And how many times do I have to feed them? I've heard different things ranging from once every two days, daily to once a week. How much more expensive are they to keep, then let's say a ball python?

Thanks!
