What Is the Lifespan of a Guppy?

The average life expectancy for a guppy is two years. Their lengthy lifespan combined with their small size makes guppies a popular choice for pet owners who want fish. Guppies tend to get along well in a fish tank and feed on fish flakes.

To optimize the lifespan of a guppy, hard water or salt water is preferred in a fish bowl or tank. Fungi and aprolegnia are common health conditions that affect guppies. Pet stores have products for tank use that eliminate these problems. Regular cleaning to remove fecal matter is also vital to sustaining guppies in a bowl or tank.
