A fish bowl is acceptable but not recommended. Goldfish produce much more waste than other fish. This requires powerful constant filtration and water circulation/oxygenation to maintain adequate water quality. Furthermore, a bowl will quickly become too small for a healthy goldfish. Ideally, one goldfish requires a tank of at least 20 gallons. If you decide on a bowl, you will need to perform partial or complete water changes daily or at least every 2 days. Use aged/conditioned water that is temperature matched to tank water. There are small filters and air pumps that may fit in a good sized bowl to extend the time between water changes. Feed once a day and use a pelleted diet that sinks. Lifespan will depend on tank size, water quality and diet.
