I want to upgrade my tank to a 125 gallon. Currently I have a 75 gallon tank. My room is located upstairs in a residential home and this is the only place I can put the aquarium. I found a good deal today for 6ft aquarium 125 gallons. Does anyone have experience with putting a big aquarium in their room? If so what was your experience? Would you recommend such a big aquarium for a 2nd story room?
