How often should i change my geckos water. and how often should i clean out the vivarium?

A geckos water bowl should consist of clean water at all times. This means the bowl must be changed and clean every day. In most cases a water bowl will evaporate if a heating lamp is present but if not, that water will turn stale, possibly grow mold and is possible to make your animal ill. The animals habitat should be cleaned monthly at a minimal.
