Amano shrimp are one of the most popular freshwater aquarium shrimp. Their algae eating habits and peaceful nature make them an excellent addition to planted tanks and peaceful community aquariums.
But how long do these shrimp live? And what does it take to keep them thriving?
Amano shrimp (Caridina multidentata), also known as Japanese algae-eating shrimp, are highly sought after in the aquarium hobby. These small crustaceans are loved for their ability to control algae and their peaceful nature. If you’re considering adding Amano shrimp to your aquarium, it’s important to understand their lifespan, care requirements, diet, and breeding habits. In this guide, we will provide you with all the information you need to successfully care for and enjoy these fascinating creatures.
How long do amano shrimp live? The answer lies on proper amano shrimp care factors.
Here are some key factors that affect Amano shrimp lifespan:
Like all aquatic life, shrimp are sensitive to water quality. Ammonia, nitrite, heavy metals, and low pH can all shorten their lifespan. Perform regular water changes and test water parameters frequently.
A nutritious diet rich in vegetables, algae wafers, and supplementary foods is vital. Malnourishment weakens the immune system and shortens life.
Amanos prefer cooler water from 65-75°F. Warmer tropical tanks near 80°F will shorten their lifespan.
Minimize stress by providing ample hides and plants, avoiding overcrowding, and keeping tank mates peaceful. Excess stress wears down shrimp.
Younger shrimp generally have a higher lifespan potential. Buy younger juveniles around 1/2 inch for longevity. Avoid large adults.
With pristine water quality, an excellent diet, low temperatures, minimal stress, and a young starting size, an Amano shrimp lifespan of 4+ years is achievable.
The lifespan of Amano shrimp is typically around 2-3 years, although with proper care, they can sometimes live even longer. It’s important to note that the lifespan of Amano shrimp can vary depending on various factors such as water quality, diet, and tank conditions. Providing optimal conditions and meeting their specific care requirements will help ensure the longevity of your Amano shrimp.
Proper amano shrimp care is the key which decides “How long do amano shrimp live”.
Amano shrimp care properly goes a long way towards ensuring they live a long, healthy life:
Amano shrimp require a minimum tank size of 10 gallons (40 liters). However, it’s recommended to provide them with a larger tank to allow for more space and to accommodate a small group of shrimp. A larger tank also provides more stability in water parameters. Amano shrimp are social creatures and feel more comfortable in groups rather than being kept individually. For every additional Amano shrimp, add an additional 2-3 gallons (7.5-11 liters) of water volume.
As a general rule, you can safely keep:
When setting up the tank, consider providing ample hiding places and plants for the shrimp to feel secure. Amano shrimp are excellent climbers and grazers, so including driftwood, rocks, and live plants will create a more natural and enriching environment for them. So how many amano shrimp per gallon is depends on proper tank setup and other parameters discussed above.
Maintaining proper water parameters is crucial in proper amano shrimp care sheet and for the health and well-being of Amano shrimp. Here are the recommended water parameters:
Regular water testing and monitoring are necessary to ensure these parameters remain stable. Keep in mind that sudden changes in water parameters can be stressful for Amano shrimp and may negatively impact their health.
Proper water filtration and flow is another serious topic on amano shrimp care requirements. Amano shrimp are sensitive to strong water currents, so it’s important to provide gentle filtration and avoid strong water flow in the tank. The best filtration option for Amano shrimp is a sponge filter. Sponge filters not only provide mechanical and biological filtration but also serve as a grazing surface for the shrimp. If you opt for a different type of filter, consider adding a sponge pre-filter to the intake to prevent shrimp from getting sucked into the filter.
While Amano shrimp do not have specific lighting requirements, providing a high-quality, full-spectrum light can promote the growth of healthy plants and algae in the tank. Amano shrimp are excellent algae eaters, and a well-lit tank will ensure a steady supply of natural food for them.
Amano shrimp are not particularly picky when it comes to substrate. They can thrive in tanks with sand, gravel, or planted substrates. However, be cautious when using substrates that lower the pH, as this can affect the water chemistry. If your tap water is already soft, a pH-reducing substrate may make the water too acidic. In such cases, it’s essential to monitor the pH, GH, and KH levels and make necessary adjustments to maintain stable water parameters.
As mentioned earlier, Amano shrimp appreciate a heavily planted tank. Live plants provide grazing surfaces for the shrimp and help maintain water quality by absorbing excess nutrients. Additionally, plants provide hiding places for the shrimp, especially after molting when they are more vulnerable. Adding driftwood, rocks, and other decorations will further enhance the natural aesthetics of the tank and create additional hiding spots.

Amano shrimp make excellent tank mates for small, peaceful community fish that won’t prey on them like:
Ember tetras, neon tetras, cardinal tetras, green neons
Harlequin rasboras, white cloud mountain minnows, chili rasboras
Sparkling gouramis, honey gouramis, peacock gouramis
Pygmy corydoras, habrosus corydoras, otocinclus catfish
Endler’s livebearers, celestial pearl danios, white cloud minnows
Ghost shrimp, cherry shrimp, crystal shrimp
Nerite snails, trumpet snails, ramshorn snails
Amano shrimp are primarily algae eaters and are highly efficient at consuming different types of algae. They can help control common types of algae, including hair algae and green spot algae. However, it’s important to note that Amano shrimp will not eat black beard algae.
In addition to algae, Amano shrimp also require a well-balanced diet to thrive. Commercially available shrimp pellets, such as Omega One Shrimp and Lobster Pellets, make an excellent staple food for Amano shrimp. These pellets contain a combination of whole fish, kelp, and other algae, providing the necessary nutrients for their overall health and growth. The pellets are also fortified with calcium, which is essential for the development of healthy shells.
To supplement their diet, you can offer blanched vegetables such as spinach, kale, cucumber, squash, and carrots. These vegetables should be blanched to soften them and make them more easily consumable for the shrimp. It’s important to remove any uneaten vegetables from the tank after a couple of hours to prevent water contamination.
Proper amano shrimp care, water parameter and other essential factors which we have discussed above are eventually decides “how big do amano shrimp get”.
However, fully grown amano shrimp reach about 2 inches (5 cm) in size. But, they are usually sold as juveniles around 1/2 to 3/4 inch long.
They grow fairly quickly and will reach their maximum size within 4-6 months under ideal conditions.
Males stay a bit smaller and slender than females. Females develop saddle like eggs under their tail when mature.
Amano shrimp breeding in captivity can be challenging and requires specific conditions to be successful. Unlike some other species of shrimp, Amano shrimp require brackish water for their eggs to hatch and develop into larvae. The larvae then need to be transitioned from saltwater to brackish water and eventually to freshwater.
Here is a quick overview on amano shrimp breeding process:
Amanos mate frequently but eggs only hatch in brackish water of SG 1.010-1.015. A mating tank with marine salt is required.
After mating, females carry eggs until they hatch as tiny zoea larvae and become free swimming. This takes 3-4 weeks.
The planktonic zoea must be fed infusoria, phytoplankton, or special powdered larval foods multiple times per day.
After progressing through several zoea stages, they morph into post-larval shrimp. These can be moved to freshwater.
The post-larval shrimp are still tiny and require green water, powdered fry foods, biofilm, etc until they grow.
Amano shrimp breeding takes dedication! Purchasing captive bred juveniles is easier but costs more. Either way, adding Amano shrimp helps create a balanced ecosystem.
Due to the complex breeding requirements, successfully amano shrimp breeding is not commonly achieved in home aquariums. It requires careful planning, precise water parameter control, and dedicated efforts. Unless you are committed to providing the necessary conditions and are experienced in shrimp breeding, it’s best to appreciate Amano shrimp for their algae-eating capabilities rather than focusing on breeding them.
Amano shrimp are fascinating creatures that offer both aesthetic value and practical benefits in the aquarium hobby. Their ability to control algae and their peaceful nature make them a popular choice for planted tanks and community aquariums. By providing them with the proper care, optimal tank conditions, and a balanced diet, you can ensure the longevity and well-being of these fantastic shrimp. Enjoy the beauty and utility of Amano shrimp in your aquarium and experience the joy they bring to your aquatic world.
Remember to monitor water parameters regularly, maintain stable conditions, and provide a suitable environment for their specific needs. With proper care, your Amano shrimp will thrive and become valuable additions to your aquarium ecosystem.
