It's a standard 125 gallon tank, there are only two possible options in my living room - if the tank were any bigger I'd hire someone to make sure, but with this tank size I feel comfortable with asking the community here.
House was built in the 1940s for reference - standard 125 gallon tank (72x18x24). I've added pictures as well and tried to use Paint to draw where the tank would be going, red = option 1, yellow = option 2
Option #1
On an interior wall
Against the floor jousts
One end would stop in the middle of an air duct/vent
Option #2
On an exterior wall
Parallel to the floor jousts
Front end of the tank would stop over the mentioned air duct/vent
Red = Option #1
The end of the tank would end over this air duct/vent thing. This duct/vent (sorry I don't know the proper terminology) is about double the width of the normal jousting width.
Yellow = Option 2
So the back of the tank would be against a joust but the front end would be on top of this duct/vent.
Lines are just trying to show how the tank would go - this kinda shows just how wide this duct/vent thing is.
