How old can a fish get?

They don't seem to mind though, as specimens of Orange roughy have been aged to a maximum of 149 years old. They are extremely slow growing organisms and can take 30 years to reach maturity. They

Orange roughy have been found in various disjunct locations across all oceans of the world at depths of between 180 and 1800 m.
