Scroll down to the arboreal setup. Bladez is right, cross ventilation is very important for a.versicolor. They require slightly higher humidity than required by most ts, and a good ventilation.
I've got my first versicolor 2 months + ago, and it's still alive and kicking.
I'm sorry for both your losses, hope the next versicolor you order will not share the same fate.




















I'm keeping 1cm avic versicolor for almost 3months (now 1.5inch) and there's no problem at all.
