i was browsing liveaquaria.com and i came across a koi article which said the longest living koi was 226 years old, is this true? do koi's really live up to that long?
Some can live up to 100 years but its more common for a Koi in good conditions, well feed and cared for to reach between 30-60 years.
some breeders claim these Koi to have been there when their father owned the business and so on.......
