I just got two giant day geckos a few days ago. I have been misting their tank 2-3 times daily and keeping the dirt extra moist because i am worried that they are not drinking water. I have a waterfall that I purchased in a corner of the tank. it is near the walls so that they can hang down and it makes a slight humming noise. Am I wasting my time with this waterfall or do they just need time to adjust to their new surroundings before they go near the slightly humming waterfall
