how long will goldfish live in a bowl
A goldfish can survive for a short time in an unfiltered small bowl or in a tank with poor water quality, but if he lives in unfit water for very long, his life will be shortened considerably. Healthy goldfish live on average 15 to 20 years, while those kept in unhealthy conditions, even well-cared-for otherwise, live an average two to three years. A filter is necessary to maintain the type of water quality a goldfish needs to live a long and healthy life. Using a filter doesn't mean you can't keep your goldfish in a bowl -- as long as it's a large one. Filters are available for traditional tanks, decorative containers and goldfish bowls.
