I think I will have the room, but cosmetics are a big thing. I am married to an interior decorator and I am trying my best to cover up as much as I can. My nano will be about a foot away from the main tank. The back of the nano tank is plastic so I can easily pop a hole in the back and add a bulkhead there.
I wish I had a picture of the proposed setup, but that's at home and alas, I am at work right now.
