who has the oldest fish?

i think its based on like how big the fish gets, i doubt a neon tetra lives TOO long, and dont rams only live 3 years? well those iradecent sharks in my signature are about 30, i wonder how big they get in the wild
 
Actually, Cardinals/Neons can live about 10 years. Danios are also a long living fish. On the other side of the coin, there are also some rather large fish which dont live for that long.

I'm not sure its a matter of the size of the fish, as much as it is the genetics of it all. There is definately science behind things, and maybe someone can give a better explaination.
 
The guy I used to buy fish from had an Asian aro in the store that he claimed was his father's before he owned it, something like 50 years old. I have heard of cases where they do live a very long time, but if this guy is telling the truth then this is surely the oldest that I have witnessed. Personally I have had mine for 6yrs so far, still going strong- Ill keep my fingers crossed for 50. That would be strange to have a fish that outlived its owner, huh?
 
i think koi/goldfish live longer because they are coldwater
 
I have five neons that I've had for 6 years...
and 3 danios that I've also had for 6 years...they look REALLY bad though, and have recently started to die off (I had 8 or 9)...
