Another Annoying Load Bearing Question

[Jaws]

Sorry guys. I hate asking this question but better safe than sorry. I've got a 92G corner bow tank on a stand with canopy and about a 50G sump. Correct me if I'm wrong but I'm estimating a weight of around 2000lbs once totally setup. The tank is in the dining room, above the laundry room, and is tucked into the corner. One of the outer corners of a rectangular house. When you're in the laundry room looking up you can see the floor joists the tank is sitting on. They're 2 by 8's and they're 18" apart. The tank stand is 38" by 38" and is evenly distributed over two floor joists. When looking at a foundation wall in the laundry room, you can see that there is the foundation wall, a floor joist, and then the two floor joists that the tank weight is on. The floor the tank is sitting on is natural hardwood then a layer of what looks like 1 by 4's and then the floor joists. Should I be concerned at all? Any input would be really appreciated. Thanks.
