With aluminum braces, you could have made braces that extended the full side. It looks like the original style is rimless, which is a aesthetic thing lots of people like. However, if you are not partial to it, I would suggest making a full aluminum rim for the top. You can drill into the areas where you need cables or tubing to go through. A full brace would even out more of the pressure on all sides of the tank.

Yeah aluminium is certainly not very rigid in itself, so it's mainly the geometry of how it's arranged, the 90 degree angle with the long side perpenticular to the front/back panes. It would be easy to bend it in the other direction, towards the short side, but towards the long side it should take some pretty crazy force to accomplish. Like how you can support the weight of a small car with a bunch of eggs if you line then up vertically, exploiting their double-curve geometry. I don't have any info on what particular type of alloy of aluminum this is though.

I guess if you siliconed it on then it would be alright. I wouldn't trust it, but in the end that it really your call. I personally wouldn't want to glue a piece of aluminum to the top of my gorgeous rimless tank.

I hear ya, I tried to keep it as a minimal as possible. There isn't any measurable bowing of the short side panels and the manufacturer didn't see a need for them so I left them out I'm gonna keep a close eye on the whole set up, goes without saying. It's conceivable that the aluminum will start to "sag" with time. I currently have a standard black plastic light hood which currently just covers up the aluminum trim completely anyway unfortunately, but if I get around to it I would love to actually run this tank open topped and maybe fix up a light fixture also with a minimalist theme with aluminum trim, so it would all fit together nicely. Maybe I can just somehow separate the lighting component of the hood and secure it to a new aluminum-themed enclosure somehow.

If it all fails I'll just suck it up and get some custom glass cut and revert to the original design! Or totally overbuild and do a full Euro-bracing while I'm at it...
