Five days ago, I bought a baby/juvenile bearded dragon (5 inches). He looked very healthy and active at the time. The setup he is in is a fifty gallon tank. I am using reptile carpet. The basking temp is between 100-112 and the cool side is around 80. I turn on the lights at 8 am and off between 8 and 10 pm. Since I got him, he has only eaten two little crickets. He won't eat. He will not touch any kind of food now. I have tried hand feeding. I am worried he is dehydrated because the skin on his back has become wrinkly. I gave him two warm baths because his tail was shedding until yesterday. He won't bask anymore and in the cage is dark colored and just lays on the floor. When I take him out, however, he gets bright and looks alert. It really worries me that he is just laying on the floor and becoming skinnier. I do not know what to do. Anyone have any ideas? Should I wait a couple days or take him back to the store so they can take him to a vet? Thanks!
