Hey guys!

I have had my whites tree frog for about a month now he is happy, plump and jumping around
I think its that time where you have to replace their plantation soil. Is one month too long? should I change it more often? or like every 2 months??? anyways the real issue I have here is how i do it! I don't wanna clean it with him in there (because i will be taking out all the plants and giving it a good ol' scrub.) But i tried putting him in a smaller container to attempt to clean his viv and he was so stressed, jumping everywhere and he turned browny/purple so i immediately took him out and he jumped around all crazy, he does not like small spaces at all. So what do I do here? i can't leave him in there, i can't put him in a box? how do i change his soil? do you guys have any methods?? Also just a quick question, I see loaaddsss of videos on the internet of tree frogs eating in the day, but mine ONLY eats in the night, like midnight. I caught him eating once but he froze and when i looked away he continued eating? is that normal for whites to be so shy about eating, i heard they would eat anything that moves XD.

Thanks lads!
