Leon the Veiled Chameleon at 15 weeks has a propensity to hang on the screens in his basking lamps. I have rearranged his plants so that they hang in the basking areas but he manages to squeeze his body in between the plants to hang on the screen still--looks mighty uncomfortable. I am worried about toenails. Any suggestions? He is in a Reptarium. I have a great thermometer so the basking temps are good.
