Or build a long, sturdy stand tall enough to stand over the fridge and tv. Two 2x8s and a 2x6 on 4x4 posts with 2x4 cross braces will give you an 8' long tank stand just over 20" wide that will easily support both tanks and you wont have to drill holes in the wall, I used to do this in the barracks and aid stations while in the army.
