I'd be concerned about the tank rocking everytime someone walks by

Without extra joist supports, you're only relying on the flooring/plywood for the front half of the tank
And from what I see, it will crack the nice trim you have from the flooring to the walls

I had a 6 foot 125g on 12 foot 2x10 beams, and against a 2x6 load-bearing wall where normally there would only be a 2x4 wall
The tank was estimated @ around 1500Lbs

An Engineer told me to not have a house party as it would not necessarily fail, but would cause the tank to start rocking and spill over or even tip over

I could stand in the middle of my Living Room and bounce my feet to make the tank rock

Put another joist in and be done with it
