It says 90 I don't know if that's correct or not.
And there is lots of foliage, a decent amount anyway. I have a big 3.5 foot tall shefflera (umbrella plant) in his cage.
They are usually happy when out of the cage and turn their pretty colors. He's probably happy when eating too. I don't think you have a temp problem. I'd keep him in the lower 80's. I'd also recommend you get a digital temp gun.
