Goldfish kept in bowls don't even live longer the 6 months!! DO NOT GET A BOWL, THEY DIE FROM A SLOW PAINFUL DEATH OF SUFFOCATION. Belive me I did a project on goldfish bowls. Click on this link to read more about goldfish bowls


It is a common belief that goldfish belong in bowls or small tanks. It is simply not true. Goldfish get 8 inches long and can live to be 10 years old or more. Those kept in small bowls or tanks only live a few weeks or so and are suffering terribly the whole time. Those poor fish simply need more room. Fish waste turns into ammonia. The ammonia is building up in there and is burning their gills, eyes and skin. They slowly suffocate as their gills become more and more damaged and they develop other problems. Goldfish need 10 gallons per fish and good filtration to avoid all that. Even if your little tank has a filter in it there is no way it can keep up in that small of a tank. The less water, the more concentration of deadly ammonia there is and the less area there is for gasses to exchange on the surface. When the tank is an appropriate size the ammonia is consumed by the beneficial bacteria that grows in the filter pads and on surfaces in the tank.
