I have a 90 gallon, 48x18x24 and my Gar is just shy of 13" I really want to move him into a wider tank but money and location won't allow me to for at least 8 months... I was wondering when should I really move him to a bigger tank? I can't have a bigger tank at my apt because I doubt my floor will hold a 120 its an older place and already bends in places on the floor. What should I do?
