I was told by our measly little towns pet store that my gray tree frog didnt need UVA but UVB was beneficial...I didnt have any light at all for the first 9 months of having her, but now I have a daylight blue bulb mostly to warm up the enclosure. I want to know what kind of light I can use at night just so I can see what she is up too. Is there a light that mimics the moon?
