How long do fish live?

[vatso]

This is an interesting question - how long do fish live?

How do we know if a fish died of old age?

Longer than we think i reckon, my sailfin has been with me for 10 years, he was at least a year or two when i got him and now still only half the size books say they get to, albeit in the wild.
