i have had my clown for 7 years. it might depend on the fish. certain fish live longer than others i believe.
IMO...a young fish may die, just as quickly as an 'old' fish...the difference should be in knowing that the old fish has done well in captivity...if it's healthy...buy it!

Smaller fish tend to have a shorter life span than larger ones such as gobies and blennies. Moreover, just because a fish is relatively large doesn't necessarilly mean that it is an old fish.
Case and point, I have a Yellow Tang that has only grown about an inch or two since I bought it. Based on its size you would think that it was maybe a few years old. However, I have had my Yellow Tang for 16 years now and he is still very healthy and full of vigor and color! Ideal water parameters, varied diet, frequent water changes, care in selecting future fish regarding compatability and health of the specimen will go far in providing your fish with the right environment to allow them to obtain and reach longer life expectancies.

I currently some freshwater Severums and parrot fish that are 15 and 16
I have been doing research in the biology of aging for 40 years, and can tell you the life expectancy of pretty much any animal, but not fish in captivity. There are just too many variables, including temperature, diet, water quality, etc. That said, most long-term aquariasts have had at least one fish live into the teens in their tank.
I have had tangs and angels for 12 years. Also there was a study on yellow tangs in particualar that showed a yellow tang in the wild only needed 6 months to reach its max size. And as stated above some yellow tangs barley grow in captivity.
