life span of fish

I think the two most important factors in fish longevity are species and source. You'll find that fish from reputable wholesalers/LFS are your best bet, because you know they have been ethically caught/well treated beforethey came to you.

Some species just don't do well in aquariums. We don't know enough, or we just can't provide the right environment. Really, when our success in captive breeding is restricted to just a few species, how well can we claim to be doing? Then are are some fish such as Moorish Idols, which plain don't belong in the hobby IMO because we can't even keep them alive for a relatively short period of time.

IMO we should stick to the ones that do okay in captivity, for the sake of the fish and our wallets...

OK...but once you've taken a fish past 3-6 months in your tank it would be hard to blame someone else if it dies after that. (assuming natural lifespan is considerably longer)

I'm just saying the obvious, I suppose...that the aquarist themselves is a significant factor in longevity.

When I lived in England I had Japanese Koi Carp and some Isreali and uk bed koi carp. My Dad is still looking after some we have had for over 22 years !

not had anywhere near the same success with tropical fish.

on a related subject my friend has a pair of African Grey Parrots, his wife was surprised to find their will has to have provision for the Parrots, as all being well they will out live them both.
