Hi I'm new to the site. I have two Russian torts, I have had them for about 12 years now. I just built them a new enclosure. It is in my opinion awesome. It is 5'6" long and 2'6" wide. I put slate tiles on the bottom with about 4" of coconut bark on top of that. I cut a flower pot in half for caves. And a ramp for climbing. I also put in a feeding rock and a rock to climb on and under. I will post some picks later.
