I just purchased 2 Bumble Bee Walking Toads and received conflicting info on care. First, do they require an undertank heater or is room temp ok? Second, I'm providing UVB light but was told not really necessary (I was told to put tank by window but I don't think you can get UVB light through glass). I mist the tank twice a day to keep humidity between 60 -80. Help, I want to make sure I'm providing proper care. They are so cute.
