20x20x20 ATB Cage

Hello im needing some help on the right size for my ATB to live her whole life out in, do you all think this size of cage would keep her happy 20x20x20 it's made by herpcages and the tank is 100.00 U.S. bucks . Here is a picture

What should i use for the perches and how many should i get?

Would i need to buy a heat panel or just use a Infered Red Heat bulb on top? Thanks Aaron

Animal Plastic should pay me for all the plugging I do for them around here....oh well, their cages are awesome so........

Heres a link to pics of their Arboreal Cages.......for some reason the arboreal cage section of the website is messed up so just call them if you see something you like.

I ordered one from him, but not arboreal. But it's just amazing, they look nice, are clean and are just perfect :).
Kinda cheap too (btw the price is in CAD $ not US).
