A stock tank is very solid, especially compared to other types of tanks. I guess you can stack a few blocks to raise it, though you won't get much space underneath it like you would with a cabinet. I guess he would be OK in a basement, provided the noise and distractions are limited.
A storage container... like the clear ones, won't last too long. If you have the space for it and are planning on a stock tank, you might as well just go ahead and get it.
