Hello, I recently bought 2 white tree frogs and they're very active, jumping about on their hanging plants etc but today I noticed one of them is sleeping on the floor under the log. The other one is on a leaf. Should I be concerned that he's on the floor. He looks healthy enough, bright eyes, a pale blue tint colour but just read up that it can mean they're ill if they're sleeping on the floor. I'm worried about this so need some clarification. Thank you in advance!
