If you are planning on putting it next to a wall, the best thing I did for the tank is build a "stage" in the back of it. It is about a foot high and 10" wide and 6' long.
Oops, should have replied to this in the other posts, but GREAT IDEA!
The only issue is that this needs to be child-safe (18 month old running around) and the cables can't be exposed since we have a pet rabbit and they chew cables relentlessly. Electrocution is the leading cause of preventable death in pet rabbits :sad:
