Hi everyone hope you are all well.
I have a little whites tree frog and he has a lovely set up the only problem is I'm unsure how long his light should be on in summer time now that it is that little bit warmer in general.

He has a 25w daylight basking spot lightbulb but at times it goes above 85f which in the long run can't be good. I tend to have it on for 12 hours a day but would he be healthier to have it less than 12h a day and just the heat mat on for longer instead.

Hope someone can help.

Thanks for reading.

Shelly.
