Hi everyone.
I have searched everywhere on how many hours a day or night my whites tree frog needs his light on but had no luck at all.
The temperature was quite low despite me spritzing the tank often so I took the shop owners and frog owners advise very recently and got a 50 watt UV light placed by the top of my tank.

I have been putting it on for a few hours in the day alongside my heat matt and having it off at night when he is awake. I am doubtful he will need the light much in summer as it will brighten up, he is hybernating a lot atm. I got him from pre loved so I didn't get told too much about lighting but more about diet and water.

I would be very grateful if someone could help me out with some advise, I don't want to cause Jumpy any harm by doing the wrong thing and not realising.

Thank you.
