How Long Do Carp Live?

Scientists can tell how old a fish is by counting the growth lines on its scales. These lines are somewhat like the rings on a tree stump—for each year of life, a new line forms.

Goldfish in home aquariums usually live about 5 years, though some have lived for more than 20 years. The oldest known goldfish lived more than 40 years. The better care you give your goldfish, the better are its chances for a long life.

Most wild carp are thought to live between 15 and 18 years. However, this depends on the species. Larger species usually live longer than smaller species.
