A fish that can live up to 60 years must be an interesting fish, if you ask me! I mean that's almost like the number of years one can live on earth.

In terms of pets, koi and goldfish live the longest. Koi live to be 20 to 25 years and goldfish live to be 10 to 20 years. Pea puffers can live to be over 18 years as well.

Goldfish live long and are easy to maintain. You can choose Angel also, but it requires special care. Oscars on the other hand are easy to maintain and they too live longer.
