I have a few questions about leopard geckos. The first one is what kind of heat bulb should I use and do I leave it on overnight? Second one is about calcium and vitamin powders and whether or not they need them and if so how often. Also what is the best way to sterilize wood decor and how often it should be done. And lastly, i'm pretty sure leopards don't need vegetables in their diet but i just wanted to check.
