I just came across this article on the oldest pacu fish that I have ever seen. His name is Buttkiss and he is 43 years old!! Wow! I hope my pacu grow to be that age. If they do grow to be that age I might not be alive myself. Lol! That is an awesome story to check out at http://articles.nydailynews.com/2010-03-08/entertainment/27058416_1_pacu-fish-story-big-fish
