The expected lifespan of guppies is generally 1 to 2 years. Under artificial breeding conditions, the lifespan of guppies is usually between 1 and 2 years. The specific lifespan may be affected by the breeding environment and management methods.

The lifespan of guppies is affected by multiple factors. First of all, the lifespan of guppies varies depending on their gender. Generally, the lifespan of female fish is slightly longer than that of male fish. Secondly, the quality of the breeding environment has a significant impact on the lifespan of guppies. If the breeding environment is poor, the physical condition of guppies may be affected, and the lifespan may be shortened to about 1 year or even shorter.
To extend the lifespan of guppies, it is recommended to provide a good breeding environment, keep the water quality clean, and change the water source regularly. In addition, a reasonable diet and appropriate temperature are also important factors for keeping guppies healthy.
