Fish tank in condo

[lorenz0]

So I decided to get a larger tank for my condo but I am in need of some advice

My building is 6 years old and it has a wood frame structure. I am on the 2nd floor and I am a bit worried about weight, last thing I need is to get a phone call that my neighbor below me has a newly acquired fish tank. I have no idea how the support beams run, I emailed the condo board asking for more info and how much dead weight one spot can take. Now where I want the tank I highly doubt its a load bearing wall (separates my room and the rest of the apartment).

I want a 60" long tank to fill the void where my tv used to be. So without having to big of a tank and now worrying the dimensions I have come up with is 60x16x16 and I have calculated it at about 850-900 pounds once everything is in it, including sump and ATO tank.

The cube I have now weights about 400-450 but it is on a load bearing wall. but it is only being distributed on a 30x20 surface area.

Think I will be ok? planning on putting a DP on the tank late this month but I need some peace of mind first
