  "summary": "The goldfish is a small freshwater fish and the world's most popular pet fish, descended from wild carp domesticated in China more than a thousand years ago. Kept in ponds and aquariums, it commonly grows to 10 to 20 cm and swims slowly, cruising rather than darting. Hardy and long-lived, a well-cared-for goldfish often reaches 10 to 15 years and sometimes more than 20.",
