Like I said frame at the top keeps the corners together. Lots of pressure on the glass. Learned that in Physics, cant remember the formula, but if your interested I could get it.

The silicone keeps the corners together NOT the trim. If the trim on the tank has no center brace than it's there to cover the sharp top edges of the tank and that's it. There is much less pressure at the top of the tank then the bottom. one could take off the bottom trim as well as the silocone between the bottom glass and the outer tank walls is what would hold it together.
