My 5 Gallon is situated on a window in my bedroom(has 1 female Dragon Tail). When it gets cold she will be moving to my desk on the otherside of my room, my window is a little drafty. That or if it doesn't fit there she will be hanging out in the kitchen all winter long haha.
In the living room, on my entertainment center I have a 10 gallon with 1 male veil tail. It is right below the TV so I find myself watching him when the commericals are in
Finally in my foyer is my 29 Gallon sorority tank that has its own stand. There was a space near my steps that were totally empty. You can see it from my living room so I do watch them too during the commercials haha
