has them listed at 5 years.... but read on.
While FreshAquarium.about.com is not a site that I normally recommend, it is one of the few I've found that have actually attempted to compile a list of fish lifespans. They probably have the numbers on the low side and used some kind of median lifespan age since they have goldfish at 10-30 years. All goldfish should live for more than 10 years and most should live closer to the 25-30 year mark. Just like many Betta sites show 4-5 years but there are more and more cases of them living longer when people keep them in a proper set up.... a filtered and heated tank, instead of a quart sized bowl/vase.
Maybe I need to start a new thread here on how long fish live and update their list to show current numbers of "How Long SHOULD fish live?", rather than how long they do live due to the overstocking, poor water parameters and stunting that shortens their lives so often.
