is our leopard gecko dying?

Question
Hello,

My husband has owned a leopard gecko for the past six years. Until a few weeks ago, he'd been in a 10 gallon tank with a red, clay-like substrate on the bottom. We alternated between the basking light and the night-glo light and he had plenty of shade area as well as a small heating pad under the tank in one of its corners. We recently bought him a new 20-gallon tank and when we were at Petco, we couldn't find the same substrate we'd had in his old tank. So the girl there told us to get the reptile sand they had there. It was a very fine, beach-like sand. We put him in there and after about a week, I noticed he hadn't eaten or gone to the bathroom. I researched on the internet and found that it was likely we had put the wrong kind of sand in his tank and that he was impacted. We emptied the tank of all the sand and lined it instead with newspaper, as I found online that would be better. We also started to bathe him for 15 mins a day in a lukewarm bath and my husband would gently rub his belly. Last Saturday, he shed his skin and ate it (we were glad he ate something). And a couple of days later, with the help of another 20 minute bath, he did go the bathroom. That was Monday. Now it's Friday and he still hasn't eaten a thing or gone to the bathroom again. He seems lethargic and stays in one place, although I have gotten up in the middle of the night and checked on him and he's been moving around more than when we're awake. His tail is still as fat as ever and he doesn't appear sick - except for the not eating, going to the bathroom, and just general fatigue. Do you have any suggestions on what we can do for him? I had read that trying to get him to drink a little Pedialyte (by dropping a little on his nose) would at least get some nutrients in him but I'm not sure. Any thoughts?

Answer
Leos tend to stress out easily, especially when there have been changes to their environment.  Give him some time to adjust.  Try to reduce the amount of handling for a few weeks.  I think he will come around and begin eating.  Just keep a careful eye on him and make sure he's not losing a significant about of weight.  

You can give him the unflavored Pedialyte, just how you mentioned. It does help to provide some nutrients.  Also, try offering him some crickets (don't leave them in the tank over night - they chew on herps).  If he begins to lose weight, you can force feed him some chicken or veal baby food with calcium, pedialyte and vitamins mixed in.
