Here's a link to someone's acrylic tank that burst.

that has noting to do with flexing and needing to be framed. plexi is not more prone to leak, if you look through that thread you will find out exactly why it burst.. very very pour workmanship. there were more air bubbles than actual glued material, they would have failed on any tank shape. this is a typical thread of a person building a tank from a hobby builder who started a company and took a job way over his skill level and failed to turn out a good product. it was very pour joints and overall pour workman ship, joints were not aligned ect.. I have done quite a lot of acrylic work, and made water features that are 6 foot tall, but I would have never taken on a take that size and shape using that thick of acrylic with out starting with smaller practic tanks to sort out the issues that I would encounter.
with a tank like that there is no more pressure on any given joint that there would be with a rectangle tank, presure is a function of hight only, the thing you are looking out for is flaws in the 90 degree corner area which could cause a week spot, so for glass tempering normaly takes care of this, acrylic if glues and cut properly won't have this issue.
