Hi There Chubaka!
Goldfish can live over two weeks without food, that's not to say you should go and starve them for two weeks of course!

But if it's just for a week, I'm sure they will be okay. If you feel uncomfortable about it, is there someone you could trust to feed (and not OVERfeed) you fish? If not if it's only for a week I would feel peace about it. Just stay away from those automatic feeders you can buy at your local fish store...they can either jam, and end up not feeding them at all, OR even worse, just dump all of the food in and your goldie, being the piggies they are by nature, will eat till they burst! That's my two cents, maybe someone else will have a good idea too! Good Luck and have fun in Arkansas!
