Weight of 15g resting on 90g?

I have a 90g in the basement and was thinking of taking my current 15g fuge and resting it on top of the 90g by putting a couple 2x4's across the the top of the 90g. Will this present problems now or in the future? The 90 is a 48x18 with 1/2 inch glass. I don't think it will but wanted to be sure first.

You wont have a problem. The 2x4's might not like it depending how you place them. If you lay them flat the 2x4 wont be able to support its full weight potential. If the are placed on there side so they sit up they will support there full weight.

I would be affraid that the downforce would weaken the upper portion corners and over time increase chance of leaks or flooding.
Also think the 90 gallon would get no light.

Hopefully a carpenter can chime in.

Weight will be fine (about 140 lbs) support your tank above from
points that are supported below on the 90 gallon.
The biggest concern you will have is the warp on the 2x4 due to the high humidity...put some 2x4 pieces 90 to the others (in between) and screw them well with some stainless screws.
Might want to throw a coat of spar varnish or varethane on the
works to seal it up...

I would be concerned about 130+ pounds on the top of the tank. It most likely will reduce the lifespan of the tank.

I disagree ..1/2 glass is 1/2" glass....If it holds it today it will hold tomorrow. It the load is straight down on the edges of the glass it is not loading up anything (silicone) BUT the glass.
