I think 10 gallon is very small. I don't really know much about size when it come to gallons, but i think 40 gallons is classed as the minimum, but I would be measuring the tank to see how big in cm/inches for the width and length.

Like Ria says can you keep an eye out on 2nd hand sites

I think you are in the States, so at this time of year I think places like Walmart have big plastic bins that are used for xmas trees/decorations, maybe have a look their and see what sizes they have available.
