Va Bene is a traditional high end Romanian kosher dairy restaurant located on the UES. Beautiful and classy decor greets you as soon as you step foot in. My husband and I had the pleasure of having Gabriel serve us more than one time.
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.
So one simple way to have a goldfish living in perfect water is to have two bowls. Each day the fish can be moved to the other bowl, while the first bowl can be emptied, wiped clean and refilled with water that will be ready for the fish to live in the next day.
