i just found this website where they make customized tanks
they will make them up to a 45,000 gallon tank
and in almost any shape and its cheap you can get a 100 gallon
glass tank for about $169. But the only problem is that they only
allow pick up(they live around LA) and they will ship to a
100mile radius around las angles, California
