The species in the tank are all very communal- they get along fine. The larger 4 are primarily vegetarian, so they sont eat the little guys.

I've had them all living together for a few years now, but just recently upgraded them into this tank.

I use fine desert sand that sifts very nicely. The only hard part is that the chuckwallas snort salty excresions all over the glass, so I have to clean it every week or 2, and it likes to smear instead of wiping right off.

I would like a good background- I have one that I used to have on there somewhere, but its only 18" tall, and the tank is 24" tall. But its better than nothing, and it is a desert theme. I'll have to look for it and try it out again to see if I like it. Maybe a fake bush or catus, or a branch inside too.
The bricks work well- they dont move, and they provide a good surface for the heat to build up on for better basking. The big blocks even give extra little sitting spots.
