No one should be frustrated, it's not that serious.By the way, there is nothing "illogical" about providing a small fish with a large space to live in in. Aside from the obvious positive that the fish will have much more room to swim around around, maintence is easier on a tank that is set up like that.
While you may not agree with it and you consider it a waste of a tank, there is no lack of logic there.
I'm frustrated by you now. So.... I'm going to ignore you lol
