They can live for a lot longer than a year if you take care of them.
If you give them a big tank (5 gallons- 19 L), condition the water and test it, dont over feed them and do water changes every week they can live for up to 5 years if taken care of properly and i have even herd a few people have had males into the ten year mark ( thats pritty exceptional thou) :) I hope that you have many year of fishy hanging around :)
