Hi everyone - I am new to this site and a new leopard gecko owner. I just purchased it 3 days ago. Lots of information out there, but I am still not sure if I need to use a heat lamp 24x7, or just during the day?? I suppose it depends on the temperature of the tank, right - just looking for some advice. And, do I need a UVA or a UVB bulb in addition to the heat bulb? Just want to make sure I avoid a mistake.
