Amano Shrimp Lifespan

Amano shrimp have a relatively short lifespan compared to some other aquatic creatures. On average, these shrimp can live for about 2 to 3 years. However, with proper care and ideal conditions, it is possible to extend their lifespan to some extent.

Factors such as water quality, diet, and the overall environment play a crucial role in determining the lifespan of Amano shrimp. By providing them with the necessary conditions, you can maximize their lifespan and enjoy their companionship for a longer time.

Factors Affecting Lifespan

Water Quality

Maintaining clean and stable water conditions is vital for the health and longevity of Amano shrimp. These shrimp thrive in slightly alkaline water with a pH level between 6.5 and 7.5. Additionally, they require appropriate filtration and regular water changes to remove any accumulated toxins and impurities.


Amano shrimp are omnivorous and have a voracious appetite for both plant matter and small organisms. To ensure their optimal health and lifespan, it is important to provide them with a well-balanced diet. Their diet should consist of algae, sinking pellets, blanched vegetables, and occasional protein-rich foods like brine shrimp or bloodworms.


Creating a suitable environment for Amano shrimp is crucial. They require a tank with plenty of hiding spots, such as rocks, driftwood, or plants. Having live plants in the tank not only provides shelter but also helps to maintain water quality and provide a natural food source for the shrimp.

Enhancing Lifespan

To enhance the lifespan of your Amano shrimp, here are a few additional tips:

  • Avoid sudden temperature fluctuations in the aquarium, as it can stress the shrimp and shorten their lifespan.
  • Maintain proper water parameters, including temperature, pH, and hardness, as per the requirements of Amano shrimp.
  • Gradually acclimate new shrimp to their new environment to minimize stress.
  • Keep a peaceful tank community. Certain fish and other invertebrates may prey on Amano shrimp or cause stress, leading to a shorter lifespan.
  • Perform regular water tests and maintain optimal water quality through regular maintenance, including water changes and filter cleaning.

By following these guidelines, you can provide your Amano shrimp with a comfortable home and help them live their best lives.


In summary, Amano shrimp have an average lifespan of 2 to 3 years. However, by ensuring proper water quality, providing a balanced diet, and creating a suitable environment, you can extend their lifespan and enjoy their presence in your aquarium for a longer time. Remember, these shrimps may be small, but they bring lots of joy and entertainment to any aquarium setup. As responsible pet owners, it is our duty to give them the best care possible.
