Is it safe/okie to have a 60g tank/stand on main floor ?

[sc2canfish]

I have a 60g fresh water tank, stand, gravel and decoration. The total weight is around 800 - 900 lbs.

I read some article online on where to put aquarium, esp this one (http://www.african-cichlid.com/Structure.htm).

At the moment, I have my tank away 10 inches from my house front wall (which I assume is the load-bearing wall), and is at the center of the house width.

for demonstration, pls go here http://pastebin.com/i0Gm7YDZ

I went to basement and check the floor joist. I found out that floor joists are parallel to the front wall. It means that my tank is parallel to the floor joist which is not the optimal setup.

I hope that the load-bearing wall will help out because my tank is close to it.

I dont know if townhouse framing structure is different than a single house ?

Please tell me if my placement is good.
