Amano Shrimp Care 101: Tank Setup, Diet, Tank Mates, Diseases & More!

If you’re looking for a unique and interesting addition to your aquarium, Amano shrimp might just be the perfect choice. These fascinating creatures are known for their striking appearance and peaceful demeanor, making them a popular choice for both novice and experienced aquarists alike. But before you bring home your own Amano shrimp, it’s important to understand the basics of their care and maintenance.

Amano Shrimp require a well-planted aquarium with neutral to slightly alkaline water. They are peaceful and should be kept in groups of at least six. They feed on algae and should be supplemented with high-quality pellets and vegetables. Regular water changes and maintenance are essential for their health.

As someone who has kept Amano shrimp in my own aquariums for years, I can attest to the fact that these creatures can be both rewarding and challenging to care for. While they are generally hardy and adaptable, they do have some specific needs when it comes to water quality, diet, and habitat. In this article, I’ll be sharing everything you need to know about Amano shrimp care, from choosing the right tank setup to keeping your shrimp healthy and happy for years to come.

Amano Shrimp

Species Summary


Amano Shrimp, also known as Caridina multidentata, are freshwater shrimp that originate from Japan.

They were first introduced to the aquarium hobby in the 1980s and have since become a popular addition to planted aquariums.


The lifespan of Amano Shrimp is around 2-3 years, but with proper care, they can live longer. I’ve had some of my Amano Shrimp for over 4 years now, and they are still going strong!


Amano Shrimp have a translucent body with a greenish-brown hue. They have a distinctive striped pattern on their back and tail, which helps them blend into their surroundings.

Their claws are long and slender, and they have two pairs of antennae.


Adult Amano Shrimp can grow up to 2 inches (5 cm) in length. However, they are usually smaller when kept in captivity.

Growth Rate

The growth rate of Amano Shrimp is relatively slow, and they can take up to 6 months to reach their full size.

However, they will molt several times during this period, and each molt will result in a slightly larger shrimp.

Behavior & Temperament

Amano Shrimp are peaceful and non-aggressive. They spend most of their time scavenging for food and algae, and they are known for their excellent cleaning abilities.

They are also active and fun to watch, especially when kept in a group.

Male vs Female

Males and females are difficult to tell apart, but females are usually larger and have a rounder abdomen.

Females also have a saddle-shaped marking on their back, which is where they carry their eggs.

Overall, Amano Shrimp are fascinating creatures that are easy to care for and make a great addition to any planted aquarium.

I remember the first time I added them to my tank, and I was amazed at how quickly they started cleaning up the algae.

They have been a staple in my aquarium ever since, and I highly recommend them to anyone looking for a natural way to keep their tank clean.

Tank Setup

Tank Size

When it comes to the Amano Shrimp, the bigger the tank, the better. I recommend a minimum tank size of 10 gallons for a small group of Amano Shrimp.

However, if you plan on keeping a larger group, a 20-gallon tank or larger would be more suitable.

A larger tank will provide more space for the shrimp to move around and explore, which is essential for their well-being.


Lighting is not a critical factor when it comes to Amano Shrimp care.

However, it is still important to provide a light source for the plants in the tank. If you plan on keeping live plants, a moderate level of lighting will be necessary.

Amano Shrimp are most active during the day, so it’s best to provide a light cycle that mimics their natural habitat.

Filtration & Aeration

Good filtration is essential for the health of your Amano Shrimp. A filter will keep the water clean and remove any harmful toxins.

Amano Shrimp prefer a gentle water flow, so it’s best to choose a filter with adjustable flow settings.

In addition, an air pump can be used to provide additional aeration and oxygenation to the water.


Amano Shrimp are native to Japan, where the water temperature ranges from 68-75°F. Therefore, it’s important to maintain a consistent water temperature within this range.

A heater can be used to achieve this. It’s best to choose a heater with a built-in thermostat to ensure that the temperature remains constant.


The substrate you choose for your Amano Shrimp tank is essential. Amano Shrimp love to dig and forage, so it’s best to choose a substrate that won’t harm them.

A fine-grained substrate like sand or gravel is ideal. Avoid using sharp or rough substrates, as they can harm the shrimp’s delicate antennae.


Amano Shrimp love to explore and hide, so it’s important to provide them with plenty of hiding places.

You can use rocks, caves, and driftwood to create hiding places for your shrimp. Be sure to choose decorations that won’t harm the shrimp.

Avoid using decorations with sharp edges or rough surfaces that can harm their delicate bodies.

Live plants are an excellent addition to an Amano Shrimp tank. They provide hiding places, food, and oxygen for the shrimp.

Some good plant options include Java Moss, Anubias, and Amazon Sword. Be sure to choose plants that can thrive in the water conditions of your tank.

When I first started keeping Amano Shrimp, I made the mistake of placing them in a tank that was too small.

They seemed stressed and didn’t move around much. Once I moved them to a larger tank, they became much more active and explored their surroundings.

Amano Shrimp are fascinating creatures, and providing them with a suitable tank setup is essential for their well-being.

Water Quality

Water quality is crucial for the health of your Amano shrimp. Here are the key factors you need to consider:

Water Temperature

I keep my Amano shrimp in a tank with a temperature of around 75°F (24°C).

They can tolerate a range of temperatures between 68-82°F (20-28°C).

Avoid sudden changes in temperature, which can stress the shrimp and make them more susceptible to disease.

Water pH

Amano shrimp prefer slightly alkaline water with a pH between 7.0-8.0. I maintain a pH of 7.5 in my tank. Avoid large fluctuations in pH, as this can be stressful for the shrimp.

Water Hardness

Amano shrimp prefer moderately hard water with a hardness between 6-8 dKH. I keep my tank at a hardness of 7 dKH.

Soft water can make it difficult for the shrimp to molt, while hard water can lead to mineral buildup in the tank.

Water Changes

Regular water changes are essential for maintaining good water quality. I do a 20% water change every week.

Use a good quality dechlorinator to remove any chlorine or chloramine from the tap water before adding it to the tank.

By keeping an eye on these key water quality factors, you can help ensure that your Amano shrimp thrive in their environment.

When I first started keeping Amano shrimp, I didn’t pay much attention to the water quality in my tank. As a result, my shrimp became lethargic and started to lose their color.

After doing some research, I realized that I needed to make some changes to the water parameters in my tank.

I started doing regular water changes and monitoring the temperature, pH, and hardness of the water. Within a few weeks, my shrimp started to become more active and their color returned to its vibrant blue-gray hue.

It was a great lesson in the importance of water quality for the health of my shrimp.

Tank Maintenance

Maintaining the tank of your Amano shrimp is crucial to their health and overall well-being. Here are a few tips that I have learned through my own experience:

First and foremost, it is important to keep the water clean. I recommend doing a 25% water change every week to remove any excess waste or debris.

This will help keep the water parameters stable and prevent any harmful buildup of toxins. In addition to regular water changes, it is also important to keep the tank clean.

I like to use a gentle sponge to clean the glass and decorations, being careful not to disturb the substrate.

It is also important to remove any uneaten food or dead plant matter as soon as possible to prevent any ammonia spikes.

Another important aspect of tank maintenance is monitoring the water parameters. I recommend testing the water weekly for pH, ammonia, nitrite, and nitrate levels. This will help you catch any issues before they become a problem.

Finally, it is important to keep up with regular filter maintenance. I like to clean my filter every 4-6 weeks to prevent any buildup of debris that could clog the filter and harm the shrimp.

Overall, maintaining a clean and healthy tank is essential to the health and happiness of your Amano shrimp. By following these simple tips, you can ensure that your shrimp thrive in their environment.

Tank Mates

Compatible Tank Mates

I have found that Amano Shrimp are generally peaceful and can live with a variety of other fish and invertebrates. Some great tank mates for Amano Shrimp include:

  • Neon Tetras
  • Otocinclus Catfish
  • Dwarf Gouramis
  • Cherry Shrimp

These species are generally peaceful and won’t harm your Amano Shrimp. Just make sure your tank is big enough to accommodate all your tank mates.

Incompatible Tank Mates

While Amano Shrimp are generally peaceful, there are some fish and invertebrates that are not compatible with them. These include:

  • Large Cichlids
  • Plecos
  • Crayfish
  • Crabs

These species are known for being aggressive and may harm or even kill your Amano Shrimp. It’s best to avoid keeping them together.

How Many Amano Shrimp Should Be Kept Together

When it comes to Amano Shrimp, it’s best to keep them in groups of at least 5-6. This will help them feel more comfortable and reduce stress.

It’s important to make sure your tank is big enough to accommodate all your Amano Shrimp and their tank mates.

Personally, I have had great success keeping Amano Shrimp with Cherry Shrimp and Neon Tetras. They all get along great and make for a beautiful and peaceful tank.

Just make sure to do your research and choose tank mates that are compatible with your Amano Shrimp.


As an aquarist, I have learned that feeding my Amano shrimp the right diet is essential for their health and wellbeing.

In this section, I will discuss what to feed your shrimp, how often to feed them, and some tips to ensure they are getting the nutrition they need.

What To Feed

Amano shrimp are omnivores, which means they eat both plant and animal matter. They are known to eat algae, detritus, and leftover fish food.

In my experience, I have found that feeding them a combination of high-quality sinking pellets, blanched vegetables, and algae wafers is the best way to provide a balanced diet.

When selecting sinking pellets, make sure they are specifically formulated for shrimp and contain all the necessary vitamins and minerals.

For vegetables, I recommend blanching zucchini, spinach, or kale and then letting it sink to the bottom of the tank. Algae wafers are also a great source of nutrition for Amano shrimp, and they love to graze on them.


Amano shrimp should be fed small amounts twice a day, preferably in the morning and evening. Overfeeding can lead to poor water quality and health problems for your shrimp.

I usually feed my shrimp a small amount of pellets in the morning and then give them a vegetable or algae wafer in the evening.


Here are some tips to keep in mind when feeding your Amano shrimp:

  • Remove any uneaten food after a few hours to prevent it from decomposing and polluting the water.
  • Don’t feed your shrimp more than they can eat in a few minutes.
  • Offer a variety of foods to ensure they are getting all the necessary nutrients.
  • Monitor your water parameters regularly to ensure good water quality.

If you want to breed Amano shrimp, you will need to set up a breeding tank with the right conditions. Here are the steps to follow:

Breeding Setup

I set up a 10-gallon tank with a sponge filter and a heater set to 78°F.

I added a layer of fine sand substrate and some Java moss for the shrimp to hide and lay their eggs on. I also added a few almond leaves to provide tannins and create a natural environment for the shrimp.

How To Breed

I started by adding a group of six Amano shrimp to the breeding tank, making sure there were both males and females.

After a few weeks, I noticed the females carrying eggs under their tails. To increase the chances of survival, I removed the adults from the breeding tank and transferred them to a separate tank.

The eggs hatched after about 4 weeks, and the larvae floated around the tank for a few days before settling on the Java moss.

I fed them powdered algae and baby brine shrimp twice a day, and within a few weeks, they became small juvenile shrimp.


When breeding Amano shrimp, it’s important to maintain good water quality and provide a varied diet. I performed weekly water changes of 10-20%, and I tested the water parameters regularly to make sure they were within the acceptable range.

I also provided a variety of foods, including algae wafers, blanched vegetables, and live or frozen foods like bloodworms and brine shrimp. A varied diet will ensure that the shrimp have all the nutrients they need to grow and thrive.

Breeding Amano shrimp can be a rewarding experience. With the right setup, care, and patience, you can successfully breed these fascinating creatures and watch their life cycle unfold.

Personally, I found breeding Amano shrimp to be a fun and educational experience. It’s amazing to see the tiny larvae grow into juvenile shrimp and eventually reach adulthood. It’s a great way to learn about the natural world and appreciate the beauty of these fascinating creatures.
