how can goldfish live in a bowl without airation? The walmart cosmetic counter has a goldfish bowl with two goldfish, and Im pretty sure that theyre the same fish everyweek. I know when I was little I had goldfish in a bowl, and in a 2 gallon tank. But when I put a goldfish that was being beatten up in a bowl for 30 minutes it died. So how is that some of them can live with out aeration?
