My tank is in our first house and we will probably not live here any longer than another 5 years or so. I have thought about the in-wall issue and also spent some time thinking about it before setting the tank up. Ideally, I would like to sell the tank with the house and then just have a new tank setup at the new house to transfer the livestock over to. But since we don't live in an ideal world, the most likely thing that will happen is I will have to take the tank down and store the livestock in holding bins while I redo the wall to sell the house. In the end, I decided the benefits of having the tank in-wall with a dedicated fish room outweigh the hassle of having to tear it down and redo the wall when it comes time to sell the house. But maybe I will think differently when the time comes to sell our house and I have to actually do it.:lol:
