Thanks for the replys already! We are using a fir bark, that he mists as needed. I do realize it is big! He does have lots of hides`and plasic plants, a water bowl, water fall, and logs for hiding and climbing. So we are going to give this one a try. We'll hang on to the other one just it case he doesn't do well. Thanks for telling me though. We will definately keep on eye on him. He's an awsome pet! Very social and a great eater.
