Night time temperature

[lexus465]

Due to the lovely warm weather we are having the night temperatures in Toa's viv are bottoming out around 80-85 deg. F. Is this too high? I know usually too cold is a concern but I was wondering if it needs to get lower than this? I can't leave the window in his room open because his humidity gets around 50% until his lights turn on. Just curious if this is something I should be worried about or not. Thanks! :?

a nighttime fan that maybe blows air out/away from the tank?...or maybe try opening the window just abit.

I myself am having some heating problems and hope you get a better answer than mine.
