If you’re a beginner aquarist or looking to add more variety to your aquarium, Blue Pearl Shrimp can be a great addition to your tank. These freshwater shrimp are known for their striking blue coloration, making them a popular choice for many aquarium enthusiasts. However, like any other living creature, they require proper care and attention to thrive.

Blue Pearl Shrimp require a well-planted aquarium with soft, slightly acidic 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.

Blue Pearl Shrimp are relatively easy to care for, but it’s important to understand their basic needs. They require a well-maintained aquarium with suitable water parameters, a balanced diet, and a comfortable environment. As a general rule, Blue Pearl Shrimp should be kept in a tank with a minimum capacity of 5 gallons, with a pH range of 6.5-7.5, and a temperature range of 68°F-78°F.

When it comes to feeding, Blue Pearl Shrimp are omnivores and will eat both plant matter and protein-based foods. You can provide them with a variety of food, including algae wafers, shrimp pellets, and blanched vegetables like zucchini or spinach. It’s important not to overfeed them, as this can lead to poor water quality and health issues. With proper care and attention, Blue Pearl Shrimp can live up to 2 years in captivity.

These fascinating creatures are a joy to watch and relatively easy to care for. Here’s everything you need to know about Blue Pearl Shrimp care:


Blue Pearl Shrimp, also known as Caridina Cantonensis, are native to Taiwan and Southern China.

They are a selectively bred species, created by breeders who wanted to produce a shrimp with a unique blue coloration.

Today, Blue Pearl Shrimp are a popular choice for aquarium enthusiasts around the world.


Blue Pearl Shrimp have a lifespan of around 1-2 years, depending on the quality of care they receive.

With proper care, it’s possible to extend their lifespan and enjoy their company for longer.


As their name suggests, Blue Pearl Shrimp are a beautiful blue color.

They have a translucent body, which makes them appear almost iridescent in the right light. Their eyes are black, and they have two sets of antennae.


Blue Pearl Shrimp are relatively small, growing to a maximum size of around 1.5 inches. This makes them a great choice for smaller aquariums.

Growth Rate

Blue Pearl Shrimp have a relatively slow growth rate, especially compared to other species of shrimp. It can take up to 6 months for them to reach their full size.

Behavior & Temperament

Blue Pearl Shrimp are peaceful creatures that get along well with other species of shrimp and fish. They are active and enjoy exploring their environment.

Blue Pearl Shrimp are also known for their cleaning abilities, as they will happily eat algae and other debris in your aquarium.

Male vs Female

Tank Setup

Setting up the perfect tank for your Blue Pearl Shrimp is crucial to their overall health and happiness. Here are some important factors to consider:

Tank Size

The size of your tank will depend on how many Blue Pearl Shrimp you plan to keep.

As a general rule, you should have at least 5 gallons of water for every 10 shrimp.

This will give them enough space to swim and explore without feeling cramped.


Blue Pearl Shrimp prefer low to moderate lighting. Too much light can cause algae growth and stress out your shrimp.

Aim for 8-10 hours of light per day, and consider using a timer to ensure consistency.

Filtration & Aeration

A good filtration system is essential for maintaining a healthy tank.

A sponge filter is a great option for Blue Pearl Shrimp, as it provides gentle filtration without creating strong currents that can harm your shrimp.

Aeration is also important, as it helps to oxygenate the water.


Blue Pearl Shrimp prefer a water temperature between 72-78°F.

A heater is necessary to maintain a consistent temperature, especially if you live in a cooler climate.


Choose a substrate that is gentle on your shrimp’s delicate bodies.

Sand or fine gravel are good options. Avoid sharp or rough substrates that can scratch or injure your shrimp.


Blue Pearl Shrimp love to have places to hide and explore.

Add some decorations, such as rocks or driftwood, to create hiding spots and add visual interest to your tank.


Live plants are a great addition to any Blue Pearl Shrimp tank. They provide oxygen, absorb nitrates, and create a natural environment for your shrimp.

Consider adding plants such as Java Moss or Anubias, which are easy to care for and shrimp-friendly.

When setting up your Blue Pearl Shrimp tank, remember to take your time and consider all of these factors.

With the right setup, your shrimp will thrive and bring joy to your aquarium for years to come.

Personally, I found that adding a few small caves and crevices for my Blue Pearl Shrimp to explore made a big difference in their overall happiness and activity levels.

Watching them explore their new environment is one of the most rewarding parts of owning these fascinating creatures.

Water Quality

Water quality is a crucial aspect of Blue Pearl Shrimp care. It affects their growth, health, and reproduction.

Ensuring optimal water quality is essential for keeping your shrimp happy and healthy.

Water Temperature

The ideal water temperature for Blue Pearl Shrimp is between 72-78°F (22-26°C).

Keeping the temperature within this range will help maintain the shrimp’s metabolism, growth, and breeding.

Avoid sudden temperature changes as it can cause stress to the shrimp and even death.

Water pH

The optimal pH range for Blue Pearl Shrimp is between 6.5-7.5. Maintaining the pH within this range will help keep the shrimp healthy and their shell strong.

Drastic changes in pH can cause stress to the shrimp and even death. It’s important to check the pH regularly and adjust it as needed.

Water Hardness

Blue Pearl Shrimp prefer slightly hard water with a range of 6-8 dGH.

It’s important to maintain the water hardness within this range to ensure proper molting and shell growth. If the water is too soft, the shrimp’s shell may become thin and fragile.

Water Changes

Regular water changes are essential for maintaining optimal water quality. You should change 10-20% of the water every week.

This will help remove any accumulated waste, excess nutrients, or harmful chemicals.

It’s also important to use a dechlorinator to remove any chlorine or chloramines from the tap water before adding it to the tank.

Personal Anecdote: When I first started keeping Blue Pearl Shrimp, I didn’t realize how important water quality was. I didn’t check the pH or hardness regularly, and I didn’t do water changes frequently. As a result, my shrimp started to show signs of stress, such as lethargy and loss of color. I quickly learned my lesson and started to take better care of their water. Within a few weeks, my shrimp started to thrive again, and their colors became more vibrant than ever.

Tank Maintenance

Keeping your Blue Pearl Shrimp tank clean is crucial to ensuring the health and happiness of your shrimp. Here are a few tips to help you maintain a healthy environment:

First, make sure to clean the tank regularly. This involves removing any uneaten food, dead plant matter, and other debris.

You should also do a partial water change every week to keep the water fresh and clean.

Second, keep an eye on the water parameters. Blue Pearl Shrimp prefer slightly acidic water with a pH between 6.5 and 7.5.

You should also monitor the ammonia, nitrite, and nitrate levels to ensure they are within safe ranges. If any of these levels are too high, it can be harmful to your shrimp.

Third, consider adding live plants to your tank. Not only do they provide a natural food source for your shrimp, but they also help to purify the water by absorbing excess nutrients.

Finally, use a good quality filter to keep the water clean and clear. A filter will help remove any debris and waste from the water, ensuring a healthy environment for your shrimp.

Personally, I found that adding a sponge filter to my Blue Pearl Shrimp tank made a huge difference in the water quality. It was easy to install and maintain, and my shrimp seem much happier and more active since I added it.

Tank Mates

One of the most important aspects of Blue Pearl Shrimp care is choosing the right tank mates for your shrimp. Here are some things to consider:

Compatible Fish Species

When it comes to tank mates, there are a few fish species that are known to be compatible with Blue Pearl Shrimp. These include:

  • Otocinclus Catfish
  • Corydoras Catfish
  • Neon Tetras
  • Ember Tetras
  • Cherry Barbs

These fish are all peaceful and won’t harm your shrimp. They also won’t compete with your shrimp for food or other resources in the tank.

Incompatible Fish Species

On the other hand, there are some fish species that are not compatible with Blue Pearl Shrimp. These include:

  • Cichlids
  • Large Angelfish
  • Bettas
  • Gouramis
  • Goldfish

These fish are known to be aggressive or have a tendency to eat smaller creatures, including shrimp. It’s best to avoid keeping them in the same tank as your Blue Pearl Shrimp.

How Many Blue Pearl Shrimp Should I Get?

When it comes to how many Blue Pearl Shrimp you should get, it’s important to consider the size of your tank. As a general rule of thumb, you should have about 10 shrimp per 5 gallons of water.

So, if you have a 20-gallon tank, you can safely keep around 40 Blue Pearl Shrimp.

However, keep in mind that the more shrimp you have, the more waste they will produce.

This means you’ll need to do more frequent water changes and make sure your tank has adequate filtration.

Personally, I started with 10 Blue Pearl Shrimp in my 10-gallon tank and they have been thriving. As they started breeding, I added a few more shrimp to the tank and now have around 20. They have been a joy to watch and I love seeing their little babies grow up!


Feeding your Blue Pearl Shrimp the right diet is essential to keep them healthy and happy. Here’s what you need to know:

What To Feed

Your Blue Pearl Shrimp are omnivores and will eat a variety of foods. They love algae, vegetables, and protein-rich foods such as shrimp pellets, fish flakes, and bloodworms.

You can also feed them blanched vegetables such as spinach, zucchini, and cucumber. Make sure to remove any uneaten food after a few hours to avoid polluting the tank.


Feed your Blue Pearl Shrimp once or twice a day, but only small amounts. Overfeeding can lead to health problems and pollute the tank.

A good rule of thumb is to feed them the amount of food they can eat in 2-3 minutes.


Here are some tips to help you feed your Blue Pearl Shrimp:

  • Rotate their diet to provide a variety of nutrients.
  • Use a feeding dish or clip to prevent food from scattering around the tank.
  • Do not feed them too much protein as it can lead to molting problems.
  • Make sure to provide enough algae in the tank for them to graze on.

Personally, I have found that my Blue Pearl Shrimp love blanched spinach and zucchini. I usually feed them once a day, and they seem to be thriving on this diet.

Remember, a healthy diet is essential to keep your Blue Pearl Shrimp happy and healthy.

Common Diseases


Blue Pearl Shrimp are generally hardy and resistant to disease, but they can still fall ill. Some common diseases that can affect Blue Pearl Shrimp are bacterial infections, fungal infections, and parasitic infections.


If your Blue Pearl Shrimp is sick, you may notice some of the following symptoms: lethargy, loss of appetite, discoloration, and abnormal behavior.

Bacterial infections can cause red or white spots on the shrimp’s body. Fungal infections can cause a cotton-like growth on the shrimp’s body.

Parasitic infections can cause the shrimp to become weak and lose its color.


If you suspect that your Blue Pearl Shrimp is sick, it is important to act quickly. The first step is to isolate the sick shrimp from the rest of the tank to prevent the spread of disease.

Depending on the type of infection, you may need to treat the shrimp with antibiotics, antifungal medication, or other medications.

You should also make sure that the water quality in the tank is good, as poor water quality can weaken the shrimp’s immune system and make it more susceptible to disease.


Preventing disease is always better than treating it. To prevent disease in your Blue Pearl Shrimp, you should maintain good water quality in the tank by performing regular water changes and keeping the tank clean.

You should also avoid overfeeding the shrimp, as uneaten food can contribute to poor water quality.

Additionally, you should quarantine any new shrimp before adding them to the tank to make sure they are healthy and disease-free.

I once had a Blue Pearl Shrimp that fell ill due to poor water quality. I noticed that it was lethargic and had lost its color. I quickly isolated it from the rest of the tank and treated it with medication.

After a few days, it started to recover and eventually made a full recovery. Since then, I have been more diligent about maintaining good water quality in my tank to prevent disease.

Signs of a Healthy Blue Pearl Shrimp

Personally, I have found that monitoring the behavior and appearance of my Blue Pearl Shrimp has been a key factor in keeping them healthy.

By paying close attention to their activity level, color, and appetite, I have been able to catch and address any potential health issues early on.

Signs Your Blue Pearl Shrimp Is Sick

If you’re a Blue Pearl Shrimp owner, you know how important it is to keep your little aquatic friends healthy. But how can you tell if your shrimp is feeling under the weather? Here are a few signs to look out for:

  1. Lethargy: If your Blue Pearl Shrimp is usually active but suddenly seems to be moving around less, it could be a sign of sickness. Observe its behavior for a few days to see if the lethargy continues.
  2. Discoloration: If your shrimp’s color has faded or changed significantly, it may be a sign of illness. Look out for white or brown discoloration, as well as any spots or patches that weren’t there before.
  3. Loss of Appetite: If your shrimp isn’t eating as much as usual, it could be a sign of sickness. Observe its feeding habits and make sure it’s still able to eat and digest food properly.
  4. Abnormal Behavior: If your shrimp is behaving in a way that’s different from its usual behavior, it could be a sign of illness. Look out for excessive hiding, swimming upside down, or any other unusual movements.
  5. Death: Unfortunately, if your Blue Pearl Shrimp has died, it’s a clear sign that something was wrong. Make sure to remove the shrimp from the tank and take steps to prevent any further sickness in your other aquatic pets. I’ve personally experienced a sick Blue Pearl Shrimp in my tank before, and it was a stressful situation. But by keeping an eye out for these signs and taking action quickly, you can help ensure the health and happiness of your aquatic pets.


If you want to breed Blue Pearl Shrimp, you’ll need to set up a breeding tank and follow a few simple steps. Here’s what you need to know:

Breeding Setup

First, you’ll need a separate breeding tank. This tank should be smaller than your main tank and have a sponge filter to provide gentle filtration. You’ll also need some hiding places, like plants or rocks, for the shrimp to lay their eggs.

Make sure the water parameters are ideal for breeding. The pH should be around 7.0-7.5, and the temperature should be around 75-80°F. Use a heater to maintain a stable temperature.

Finally, add a male and female Blue Pearl Shrimp to the breeding tank. It’s best to choose healthy, active shrimp that are at least six months old.

How To Breed

Once your breeding tank is set up, the shrimp will do the rest. The female will lay eggs, and the male will fertilize them. The eggs will hatch in about two weeks, and the baby shrimp will be fully formed in about a month.

Make sure to keep the water clean and well-oxygenated. You can feed the shrimp small amounts of high-quality food, like algae wafers or shrimp pellets, but be careful not to overfeed.

After the baby shrimp hatch, you can move them to a separate tank or leave them in the breeding tank. Just make sure they have plenty of hiding places and clean water.


Blue Pearl Shrimp are relatively easy to care for, but breeding can be more challenging. Make sure to monitor the water parameters and provide plenty of hiding places for the shrimp to lay their eggs.

If you notice any problems, like low survival rates or poor water quality, you may need to adjust your breeding setup or seek advice from a shrimp expert.

Personally, I’ve found breeding Blue Pearl Shrimp to be a rewarding and fascinating experience. Watching the baby shrimp grow and develop is truly amazing, and it’s a great way to learn more about these fascinating creatures. So if you’re up for a challenge, give breeding Blue Pearl Shrimp a try!
