Can I cut down a 20gl hex?

I found a nice clean 20gal hexagonal tank at a thrift store. Of course I bought it. It's nice and all, but I would like it to be shorter. I really don't care too much for tall tanks. My question is can I cut the tank down in size? If so, how would I go about it? Can I use a simple glass cutter? Any ideas?

you could do a riparium set up with it and have it half full that would look nice

No. Sell it and use the money to buy a tank that you like.

If you haven't done a lot of work with glass in the past, I think your chances of getting the tank cut down to the exact same height on all six panels with a simple glass cutter are pretty slim. Even if you did get it right, the resulting sharp edges will make you think you should've left it alone, and if you try to remove the trim from the cut off pieces you won't think any better of the project. If you paid $10 or similar I'd take the chance if you have the time to invest, otherwise try to break even on it if the tank height bothers you that much.

I don't have much experience cutting glass, but it sounds like cutting glass while it's part of an aquarium would be tricky at best. I imagine the more sides, the trickier.

This would probably involve building a custom stand, but I think that would be easier then cutting down a tank.

Make the stand so the aquarium sets down in it, and then put a bunch of inert substrate (gravel, lava rocks, whatever)to fill the excess bottom volume that you don't plan on using.
