Hahahahaha OP's response. Not really tall enough for an arboreal species but BHP and woma's would do well in it. You could have and of the ants or even halve it and have 2 ants. However, you end up wasting a fair bit of height as they don't really need 60 cm tall enclosures. So if you were to heat from above it would need to heat more area than necessary and reach far enough.
Monitors would be good as many monitors will climb to some extent. Have a bit more of a look as to what takes your fancy, what you can legally keep where you live and what you feel you could manage then with more info, we can give you more detailed responses.
oh and don't bother posting in different sections.
