Can I put the fish tank upstairs in the duplex building?

Of course. Duplex building has a solid structure, and its space will lead to dry indoor air, which will have an impact on human body. Putting a fish tank upstairs can replenish the water in the air to a great extent. Duplex building is a kind of building type, which is actually two floors, rather than one floor divided into two floors. Each floor has its own independent standard height, but there is a * * * intercommunication space between the two floors. From the downstairs, you can see the corridors and railings upstairs.
