So to clarify the location issue: Go to Profile on the top of the page and enter the name of the state/province/country where you live, and if you wish to be more precise you can add the town too. It's part of the rules you see.
As to your fish: You may need a new tank right now, but eventually your fish will outgrow any tank you can buy ready-made, and you'd probably need a pond of 20 x 10 foot (6 x 3m) that maintains a temperature of around 20'C/70'F or higher throughout the year. These fish grow to about 5 foot in nature, and there's nothing other than bad care that will stop this natural growth in captivity.
Unfortunately, this is not always advertised by shops (and some outright lie and say "the fish will only grow to the size of your tank" - which is a widespread myth based on the fact that some fish are able to cope with poor water quality by not growing any more - but that's a pretty cruel way to prevent the natural growth - imagine if you weren't allowed to grow above four feet because the toilets couldn't take the waste-product and you'd stop eating because of the stink in the dining room? Not a nice way to grow up, is it?
