I changed his water and will see if I can pick up some CGD at another Pet Store since I really don't feel like waiting for my usual pet store to order me some.. He can sometimes be sidetracked.

I tried to tilt the 10 gallon and I don't feel it's very safe... I don't want it to tip over when I'm not around and hurt him. Would it be alright if I use it regularily and provide a lot of high climbing places? Or is it absolutely necessary to have more then 12" of height?

Any more information would be greatly appreciated... I feel so newbie!
