Few goldfish even reach half this size. The longest goldfish so far measured 18.7 inches (from snout to tail-fin end), and was discovered in Hapert, Netherlands in 2003.

That is, given the right conditions, a goldfish can live up to 20 to 40 years. However, their usual life span reaches only up to five to six years due to being kept in smaller aquariums.
