Full Answer

Goldfish do not survive long in bowls because the lack of a filtration system allows ammonia and nitrite to build up, which is poisonous to the fish. Goldfish that are kept outdoors in a pond and fed the proper diet live an average of 20 years, and in China, goldfish have been recorded to live more than 40 years. In aquariums, goldfish live an average of 10 years as long as they are not overcrowded.
