I'm not entirely sure why, but my ball refuses to stay in his two hides but prefers to lay just under on layer of newspaper. I have two hides, a large water bowl, temps are in check etc. He does seem to understand the hot/cool difference since hell sometimes be chilling under the newspaper on one side of the tank, sometimes he'll move over to the other side of the tank, completely ignoring the two hides. I've tried both the natural store bought reptile hides and a plastic colored tup o ware with entry holes, both to no luck After I pick him up I'll put him back by laying him down on the newspaper and putting his (plastic) hide over him, but instead he chooses to go out of it and hang under the newspaper. Is it something I should worry about, or is normal? Is something wrong in the tank I've overlooked? He's about 24'' long in a 20g long tank.

Thanks
