Hey people, im new here and also a new leopard gecko owner. So i got him 6 days ago and put him in a 20 gal long tank with reptile carpet. I use a under tank heater (UTH) to heat up his warm side. He has 3 hides, 2 on the warm side and 1 on the cool side. The temperature for the warm side reads 93.5 degrees F. The first day i brought him home he looked pretty healthy (had a nice and fat tail) and ate 3 crickets and a mealworm. The next day he only ate 2 crickets and has been eating 2 crickets every night until last night (he did not eat). I had been noticing that his tail was getting A LOT smaller every day and his skin has a darker color and i know that's an indication of malnutrition. I noticed that he shedded last night because he was very pale and this morning i found some skin in his moist hide. Rocco (his name) doesnt look sick, he is very active so i dont know whats wrong with him he just wont eat the dusted crickets. Is it because he is still adapting to the new environment!? or is my tank too big for him? I know it takes them about a week to adapt but do they starve themselves? I really dont wanna take him back to the petstore because he is a pretty cool bell albino and I wanna keep him. Am I doing something wrong? I also tried to feed him waxworms (to try to fatten him up a bit) and he is just not interested :/. oh BTW when he shedded he did not eat his skin or at least not all of it (I was sleeping), i dont know why but i found some skin in the humid hide. I'm gonna try to feed him again tonight but we'll see what happens. :/
