Looking for a big octagon fish tank my father had one

Looking for a big octagon fish tank like 6ft tall maybe like 16in wide. Anyone know how i could buy one without spending a fortune?

 

Used at a lfs might be the cheapest option. Unless you have a store that does dollar per gallon sales.

Idc if its used but ive been looking all over and cant find any im willing to spend a decent amount but definitely not over like 800

 

Those aren’t very common at all. So especially if you want one of that height it might have to be custom made which isn’t very cheap
