What is the oldest Betta fish on record?

To the best of my knowledge no one keep those kind of records. Bettas are mature at 12 months, past their prime at 2 years old and ancient fish at 4 if they live that long. I have a Betta fish that is now over 5 years old because I change the water once a week with 2 gallons of purified water and I add about 20 drops of Splendid Betta Complete Water Conditioner to it. Using the water conditioner is a MUST to ensure that your Betta fish will live a very long life. I also feed my Betta fish 4 pellets of Hikari Betta Bio Gold once a day in the morning and 1 pellet at around 7pm.
