I forgot to add this. I was hoping for an in-wall fish tank, hopefully facing the great room etc. in my mind it could be inset in a wall that could be accessed from behind, like thru the bathroom in the guest/teen suite (not visible on that side, just easy to access and clean and get water in easily). My current fish tank is relatively small 2.5' X 2'. Would go bigger but not smaller. I'll be replacing it when we move anyway so if there's a place like this for it I can find a tank to fit. I feel like this is too small a detail but I don't know where your limit for that is.
