Oooo..common mistake. That is not a yellow tree monitor, but a Quince Monitor. It's nice and gentle at the moment, but once it's in the cage with the correct temps and humidity it'll be a monster. Also..if you correctly do the enclosure, which is lot's of foliage and branches..you'll start suffering from empty cage syndrome. I hope you did your research because this animal will get big and will eat lots and lots of insects. Not being rude, just giving some friendly advice
