Someone on FB is recommending UVB bulbs like ZooMed Reptisun 5.0 UVB Fluorescent bulbs or the Exo-Terra Reptile UVB Bulb... however these say they are for "diurnal reptiles"... WTFs, however, are nocturnal... so my question is this, most reptiles are not nocturnal like the frogs are... if the frogs are being supplemented with Calcium, D3, etc, on their food stuffs are the lamps completely essential? Especially considering a lot of frogs just hide in the shade of their leaves, plants, hides, substrate during daylight hours...?

His reply to my question: "The WTF comes from a large distribution area in australia... mainly queensland and from thick rainforest areas to sclerophyll forest area (gum trees, etc, lots of light gets through), in these areas a good amount of UVB still is available at ground level, in denser more rainforest areas they sleep higher up so they still get some UVB.

also there are plently of scientific papers outlining the need for UVB in WTF's and D3 absorption."

So... UVB Lamps + WTFs = Yes? No? Maybe...??
