I got a baby leo about 3 or 4 days ago and the lady at the pet store was great assistance to me, she seemed to think my gecko has a great terrerium. I'm not positive if shes had any experience with leopard geckos first hand so I thought I would post on this forum as I know majority of you do! I have bark chips as a bottom for his tank, I wouldn't prefer to stay away from paper towel if possible, would anyone suggest any other substances such as digestable sand? I have an over-head day light (75 watts), the average temperature of the warm sidebeing about 83 degrees Ferenheit, and the cool side being about 76-77 degrees. Are these temperatures acceptable, if not, what are some changes I could make? At night, I turn the light off and turn his night time light on (purple 75 watt). I have heard alot of people using heating pads but if possible I would like to stay away from those also, but if its best for him of course I will change my opinion. How would I go about setting one up? I have a small plant for him to hide behind, two hides, one on each side of the tank, a small piece of wood - mainly for decoration, the hide on the warm side is made of rock so he often lays ontop to bask. I have a shallow water dish and I feed him every other night - about 12 mealworms each feeding wth calcium of course. He is in a 20 gallon tank. I want my gecko to be happy with his surroundings and for him to be as healthy as possible so I would really appreciate some feedback and advice that would improve my tank!! Thank you so much for your help.
