Hello there, I adopted another bearded dragon yesterday. He came with a Exo Terra tank which is 900 wide, 450 deep and 900 high! Not sure why the last owners chose such a high tank but that's what he has got. The lid was also changed to a plywood one which has no air circulation. I guess that was done to keep the heat in. The UVB light is mounted right on the top, so I guess that needs to come down a bit. My question is, has anyone got a high tank for their beardies and how can you use the space best and still make everything work?
