Is this too much weight for my room?

Hello! Forgive me if this is wrong thread, mods please move it accordingly. So I currently have a 15 gallon in my bedroom I share with siblings. I'm looking into adding a 16 and two 5.5 gallons to the room along with 15. Is that okay??

I did my research on load bearing walls and im putting plywood on shelfs and under shelf for extra support. Although it's complicated to get stand at window cause my bed is there (cause exterior wall are load bearing).
This is where I currently have my 15, its near the window. Is that good? it's been there for 4 months and doing good. My neighbor used a studfinder and found studds running across wall. He told me stud finder can't locate nails on floor. so idk if they run perpendicular to wall nails.
The beds in my room including mattress weigh roughly 300 something pounds and my tanks with gravel and stand included are gonna way 514 pounds.

I forgot to mention I'm on 2nd floor apartment and there is a room on other side of wall and my living room on other.

Pics of studs we found on wall, my floor, and where my tanks will go are below

DETAILS ARE BELOW
Room size: roughly 13 1/4 in length X 12 FT width

 

It's probably fine. A 16 gallon tank, with water, weighs less than an average sized person.

It's gonna be on the same wrack as my 15 and two 5 gallon tanks

 

You’ll be fine. Even in an apartment upstairs you’d be fine.
I have a 75 gal tank and a 20 gal quarantine tank in my bedroom right now! (The QT tank is temporary)
But my house was built in the year 1900… so my floors are old, uneven in some spots, and pretty creaky most of the time. Despite my house being 121 years old — my tanks have always been fine. (And we’ve not ever remodeled the floor nor have we ever done any updating or changing it. They have been the same old floors forever!)
Just make sure that your tanks are always 100% level.

 

As far as the floor you should be fine,floors can hold a lot of weight if you had a dozen people over thats at least 1500 pounds or more not even counting the other things in the room,i know a guy who has 4 tanks and hes on the 7th floor,As far as the rack just make sure it can hold that weight.

You'll be fine with those tanks, the load spreads pretty evenly. In my case I have an old farmhouse to work with so I don't worry about the structure on any floor until I hit about 500lbs in any single tank. Even then the only consideration is what is below the floor like walls or foundation., Jack posts etc
