Cresty Troubles

[concept3]

Hi, I bought a crestey oct. 2 at the edmonton reptile show and since then I posted that he was sleeping on the bottom and you guys said It was normal. But know I moved It into a 21 gal rubbermaid and since then he just lays on the bottom in the open and sleeps. another thing I noticed this morning when I went and opened the lid of his enclosure he tried to run and hide but he could not climb the side of the enclosure? Now any ideas here? All my other cresties have no problems climbing the sides of the 21 gal rubbermaids, and I checked his feet for retained sheds. I threw some crickets in their last night and he ate them fine but he hasnt been eating his fruit mixture . Any ideas? Im really worried and its driving me nuts
