A few things:


- I would not build anything out of plexi-glass!!! It scratches very easy!!! You want polycarbonate.

- On a cage that size you will need at least 1/4"+++++ thick material with lots of glued in bracing. Lots of $$$$

- I can tell you already if you build this cage the way you should build it, it will cost much more than a glass tank. If it was cheaper, everybody would already be doing it.

- You may want to build a wood framed cage with glass inserts.

- If it were me and I wanted a clear cage, I would go with a 30-40gal breeder tank.
