I know highlanders need cool nights but how warm must their day times be? Is 70*F / 20*C ok or must the days get as high as 80 / 25*C? Since summer is over I can dispense with the A/C at night and just suck air from outside with a round duct fan in the window and cool the tank appropriately overnight but the daytime temps now don't get over 75*F / 23*C usually they hover around 70*F / 20*C. Will this be appropriate or will I need to get a heating mat for winter?
Thanks for your thoughts!
