Whats wrong with keeping goldfish in bowls?
If you’ve read this far, the problem is obvious. Goldfish outgrow even the largest bowls. Bowls are also usually unfiltered with still water so the fish suffers from poor water quality and lack of oxygen. It is possible to house a baby goldfish in a two gallon bowl for a short period of time, but bowls are never suitable long-term homes for goldfish.
