How Long Will Your Fish Live?

While researching the fish names, Caryl Simpson of New Zealand's Marlborough Aquarium Club, came across this interesting little piece...

Few reference books include one of the most common questions asked by fish owners. How long should my fish live? The answer varies greatly depending on the species of fish. However, in general smaller fish have a shorter lifespan than larger fish, and fish that lay eggs live longer than those that give birth to live young. The two most popular species of fish, Siamese Fighting Fish, Betta splendens, and Goldfish, Carassius auratus, are at opposite ends of the spectrum. Bettas live little more than two years, while Goldfish live for decades.

Here is a reference with the expected lifespan of popular aquarium fish. These figures are estimates, with good care fish may live much longer.
