Species Profile

Blue pearl shrimp (Neocaridina davidi var. blue) is part of the dwarf shrimp family. They are visually stunning and valuable to a tank’s cleanup crew. Their small size allows them to navigate tight spaces and reach areas that larger cleanup crew members may be unable to access.

Blue Pearl Shrimps Origin

The Blue Pearl Shrimp is a fascinating aquatic creature that originates as a blue variation of Neocaridina cf. zhangjiajiensis. With their stunning blue coloration, these shrimps have become a popular freshwater aquarium species. Many people may not know that they originated in captivity in Germany through selective breeding by Ulf Gottschalk.

Blue Pearls Appearance

While most of these shrimps display a vibrant shade of blue, there are also subtle variations and hybrids that exhibit different hues, patterns, and intensities of blue. Some individuals may have deeper or lighter shades of blue, while others may showcase intricate patterns or speckles on their bodies.

Juvenile blue pearl shrimp are significantly smaller than adults, typically measuring around 0.5 inches in length. As they mature, they gradually reach their maximum size of approximately 1 inch, showcasing their vibrant blue coloration and becoming a beautiful addition to any aquarium.

Blue Pearls from Other Dwarf Shrimp

Blue pearl shrimp is a unique species that stands out from other species due to its striking blue coloration.

Unlike other shrimp species that typically have a transparent or brownish color, these have a vibrant blue hue. This distinct coloration results from breeders choosing and breeding shrimp with the desired blue color genes.

Blue pearl shrimp are relatively small, typically reaching about 1.5 inches long.

They are known for their peaceful nature, unique appearance, and ease of care, making them a great addition to any freshwater aquarium.

Blue Pearl Shrimp Care

Overview: Introducing The Blue Pearl Shrimps in a Tank

Blue Pearl Shrimp are known for being relatively easy to care for. Their hardy nature and low maintenance requirements make them an ideal option for beginner aquarists.

They can thrive in various aquarium setups with proper care and attention. Whether you are a seasoned shrimp keeper or just starting, this section will provide you with all the information you need to ensure the health and well-being of these Shrimp.

Tank Setup

The tank size should be appropriate for the number of shrimps you plan to keep. A 10-gallon tank is usually sufficient for a small group of blue pearl shrimps.


They prefer a temperature range of 72-78 degrees Fahrenheit. The pH level should be around 7.5, and the water hardness should be between 4-6 dGH.

Live plants, such as java moss or anubias, provide aesthetic appeal and natural hiding places for the shrimps. Adding shrimp flats, which are small, flat surfaces, can also provide additional hiding spots.

Using black substrate can enhance the vibrant blue color of the blue pearl shrimps. The dark background created by the black substrate makes the shrimp’s color stand out more.

Choosing filters with a gentle flow is important. Blue pearl shrimps are sensitive to strong currents, so a sponge or filter with adjustable flow settings would be ideal. A pre-filter sponge can also prevent baby shrimps from being sucked into the filter.

Temperament and Tank Mates

They are known for their peaceful nature. They generally get along well with other tank inhabitants and rarely show aggression towards their tank mates. However, due to their small size, choosing compatible tank mates can take time and effort.

Dwarf shrimp, such as Cherry Shrimp or Amano Shrimp, make excellent companions for Blue Pearl Shrimp.

Snail species like Nerite Snails or Mystery Snails are also compatible tank mates for Blue Pearl Shrimp. They help maintain the tank’s cleanliness by consuming leftover food and algae.

Algae eaters like Otocinclus Catfish or Siamese Algae Eaters can also be considered compatible tank mates. However, it is important to ensure enough food is available for both the shrimp and the algae eaters to avoid competition.

Species to Avoid

Certain species should be avoided as tank mates. Aggressive or larger fish, such as Cichlids or Barbs, may view the shrimp as prey and pose a threat to their safety.

Potential Diseases

One of the critical factors in preventing diseases in blue pearl shrimps is maintaining water stability. Fluctuations in water parameters, such as temperature, pH, and salinity, can weaken the shrimp’s immune system and make them more susceptible to diseases. Regular water changes and proper filtration are essential to check ammonia and nitrate levels, as high levels of these toxins can lead to serious health issues.

There are a few common diseases that blue pearl shrimps are prone to. Bacterial infections can manifest as discoloration, lethargy, or abnormal behavior in the shrimps.

Another common issue is parasitic infections, where external parasites such as flukes or worms attach themselves to the shrimp’s body, causing visible damage to the shrimp’s exoskeleton.

Prompt treatment is crucial to prevent further deterioration. Quarantining and treating affected shrimp with appropriate medications can help combat the infections. It is essential to follow the instructions provided with the medications and consult with a knowledgeable aquarium professional if needed.

Food And Diet

These shrimp are known to thrive on a diet that includes a variety of algae, such as spirulina and chlorella. Algae provide essential nutrients for these shrimp and help promote their vibrant blue coloration.

Blue pearl shrimp can also eat other shrimp food options. Vegetables like spinach, zucchini, and kale can be blanched and offered to the shrimp.


Another food option to consider is Indian almond leaves. These leaves are rich in tannins and other beneficial compounds that can enhance the overall health of the shrimp.

Offer small amounts of food at a time. Overfeeding can lead to water quality issues and negatively impact the health of the shrimp. Observing the shrimp’s behavior and adjusting the feeding schedule is crucial for their well-being.

Average Lifespan

Blue pearl shrimps have an average lifespan that can be influenced by various factors such as genetics, habitat, water conditions, and diet. These factors are crucial in determining the lifespan of blue pearl shrimps.

Breeding Blue Pearl Shrimps

Breeding them is a relatively simple process requiring specific conditions and careful attention. These beautiful shrimp can be bred successfully in a home aquarium if their needs are met.

They require a stable water temperature and pH. It is crucial to maintain good water quality by regularly monitoring ammonia, nitrite, and nitrate levels.

They are known to be prolific breeders, with female shrimp capable of producing eggs every 30-45 days. The breeding process usually involves male-female interactions, where the male shrimp will chase and court the female. Once the female is ready to spawn, she will carry the eggs on her pleopods, which are located on her abdomen.


Gestation is a process or period of development between conception and birth. The gestation period for Blue Pearl’s eggs is approximately 3-4 weeks.

The eggs will gradually develop and tiny eyes will become visible. Providing hiding spaces, such as moss or plants, is essential for the females to attach their eggs.

After the eggs hatch, the shrimplets will be very small and vulnerable. It is crucial to provide them with plenty of hiding spaces and a source of algae, as they rely on it for their nutrition.

Avoiding Interbreeding

Avoid interbreeding with other Neocaridina davidi varieties because interbreeding can result in offspring with different colors and patterns, which may not meet the desired traits of Blue Pearl Shrimp. To prevent interbreeding, keeping Blue Pearl Shrimp in a separate tank or carefully is recommended.
