* Strain or Variety: Different guppy strains may have slightly varying lifespans. For instance, some fancy guppy varieties, such as the Endler's guppy, tend to have a shorter lifespan compared to more common guppy strains.
* Water Conditions: Guppies thrive in clean and well-maintained water. Poor water quality, including high levels of ammonia or nitrite, can significantly shorten their lifespan by causing stress, illness, and weakened immune systems.
* Diet: A nutritious and balanced diet is crucial for guppies' overall health and longevity. A varied diet that includes high-quality flake foods, live or frozen foods (like brine shrimp or daphnia), and occasional vegetable matter can contribute to a longer lifespan.
* Care and Environment: Providing guppies with a suitable and comfortable environment is essential. This includes maintaining a stable water temperature, adequate filtration, and appropriate tank size to accommodate their swimming and breeding needs. Stressful conditions, overcrowding, or lack of hiding spots can shorten their lifespan.
Generally, with optimal care, good water conditions, and a healthy diet, guppies can live for up to two years. It's important to note that female guppies tend to have a slightly longer lifespan compared to males. By closely monitoring their environment, providing proper nutrition, and ensuring regular maintenance, you can help your guppies live longer and enjoy a better quality of life.
