I am planning on starting up my first tank this spring. Being married i need to ensure my wife approves of size, placement, look, etc. Right now the idea she likes the most is a 5-6' x 18 x 18 set up behind the couch with the stand built 6" deeper and a few feet wider to accommodate drinks, popcorn, remotes, pictures, trinkets etc. While I am fairly handy, I am no carpenter or engineer. I have some concerns about the significant weight of the tank not falling squarely on the frame. Should I avoid this placement? Are there any structural issues i should be worried about? Are there potential problems that, being a noob, I have completely ignored? I would welcome and appreciate all opinions and ideas because if this goes south its all my fault if the basement is flooded with fish and 100+ gallons.
