I was wondering what recommended range of nighttime temp. is for bearded dragons? It's funny, becuase all these supposed "Expert" books go on at length about optimal basking sites and all sorts of stuff for daytime temperatures, and then COMPLETELY leave out any discussion of night. How cold can it get and still be ok? I am asking becuase the house is being kept cooler with the AC on. I don't want my guy to get too cold.
