Everything You Need To Know About Blue Pearl Shrimp

Blue pearl shrimp are magnificent freshwater creatures that can thrive in a variety of conditions. For this reason, they are a popular choice for aquarists who want to add peaceful color to their aquarium!

This guide will teach you everything you need to know about these creatures and how to care for them.

Species Summary

The blue pearl shrimp (Neocaridina cf. zhangjiajiensis var. blue) is a unique addition to your tank’s cleanup team. This species of dwarf shrimp is a relatively new addition to the aquaculturist community. It is a blue variant of Neocaridina cf. zhangjiajiensis which was originally bred in Germany.

Thanks to its pearly blue color, it quickly became a species of freshwater shrimp sought after by enthusiasts all over the world! These invertebrates are docile and easy to care for in the right conditions. They have healthy appetites and will work alongside other algae eaters to keep your tank clean.

Meanwhile, the turquoise coloring makes these shrimp stand out. Whether you have a heavily planted aquarium or one that uses rocks and modern decor, these beauties are a welcome addition.


These creatures resemble other dwarf shrimp species. They are small, conical and have severed tails. Long antennae on their heads help them navigate their surroundings, while tiny swimmers move beneath them to move around.

The color of shrimp is light blue, but there are many variations. Some shrimp will be almost pearly white or turquoise. The most popular shrimp are darker blue. In most cases, the most dynamic specimens are female.


Don’t expect to have these shrimp for very long. The lifespan of most blue pearl shrimp is one to two years.

As always, the creature’s lifespan depends on genetics and living conditions. There’s not much you can do to avoid genetic predispositions, but you can be vigilant about their habitat, water conditions, and diet. Proper care can extend lifespan to help you enjoy these beauties as much as possible.

Average height

Blue pearl shrimp belong to the dwarf shrimp family. Juveniles are usually less than half an inch long. Adults will reach just over an inch long when mature.

Blue Pearl Shrimp Care

Blue pearl shrimp are among the most accessible invertebrates to raise in captivity. They are low maintenance, undemanding and peaceful. But as always, they have preferences.

Follow these blue pearl shrimp care guidelines if you want to give them the most comfortable life possible.

tank size

Blue pearl shrimps do not require a lot of space, thanks to their small size.

They are perfect for a monospecific nano tank. However, the best results are achieved with habitats that can hold at least 10 gallons.

A 10 gallon tank provides room to move around. It also gives you more flexibility in creating a natural environment conducive to the shrimp’s way of life.

Water parameters

This species of dwarf shrimp is very adaptable. They do well in standard tropical water conditions. Therefore, you shouldn’t have to make many adjustments to help these invertebrates thrive in established aquariums.

As long as you stick to the following water parameters, shrimp will do just fine.

  • Water temperature: 68 to 80 degrees Fahrenheit (about 75 degrees is ideal)
  • pH level: 6.5 to 8.0 (near-neutral conditions of 7.2 are best)
  • Water hardness: 7 dKH or up to 20 dGH

What to put inside their tank

Here’s where you can get a little more creative! Like the water conditions, blue pearl shrimp are not demanding when it comes to aquarium decoration. However, there are a few things you can do to improve the life of the shrimp while bringing out their color.

The first is to use a dark colored substrate. Shrimp will spend most of their life at the bottom of the aquarium. Dark-colored sand or earthy plant substrate brings out the blue coloring. Fine sand or something with a similar consistency is ideal for safety.

Plants are not a requirement, but they are ideal. Plants can significantly improve water quality. They remove harmful contaminants, boost oxygenation, and give shrimp plenty of places to hide. Additionally, plants can develop algae that shrimp eat.

Get creative with your plant arrangement. These shrimp like density but also leave open spaces.

Author’s note: Don’t forget to use sponges on your filters! These shrimp are too weak for high power pumps and strong suction. Always use sponges to ensure prawns don’t get sucked into your filters.

Potential illnesses

With blue pearl shrimp, water stability is the most important thing. Check water parameters frequently and test for ammonia and nitrates. High levels of ammonia and nitrate can kill these shrimp surprisingly quickly.

While shrimp cannot catch Ich like fish, the stress of poor water quality can take its toll. This makes the shrimp susceptible to bacterial infections which eventually end their lives.

Change about 30% of the water every week. This way you can control ammonia and nitrate levels. It is also important to wait until you have a fully cycled tank. Adding your blue pearl shrimp to an unrecycled tank could spell disaster.

Food and diet

These shrimp are small, but they have a big appetite! The blue pearl shrimp will spend most of its time foraging for food. They love to eat algae that sticks to plants and decor.

But make no mistake: seaweed alone is not enough to keep shrimp healthy. You need to supplement their diet to make sure they get all the nutrients they need to thrive.

Any sinking pellets will work well as a staple for their diet. These invertebrates are omnivorous, so they are not picky eaters. You can also provide blanched vegetables, flashing seaweed wafers, and other similar items.

Behavior and temperament

Aggression is not a problem with the blue pearl shrimp. They pose no threat to other fish or invertebrates in the tank and rarely fight with each other.

They are the epitome of a peaceful tank dweller!

tank mates

The biggest challenge you will have with blue pearl shrimp care is determining which tank mates they can cohabit with. Because they are so small, blue pearl shrimp often become the target of hungry fish. Never keep them in the same tank as aggressive freshwater fish. These guys won’t stand a chance!

Your best bet is to keep the blue pearl shrimp with other nano-invertebrates. This includes other dwarf shrimp species and peaceful snails. They also do well with docile algae eaters.

Here are some good choices if you want to include blue pearl shrimp in a community aquarium.


Raising blue pearl shrimp is easy. The only requirements are to have one male shrimp and one female shrimp in a well maintained aquarium. The shrimp will do the rest!

This species is a prolific breeder in captivity. The blue pearl shrimp spawns every two to three months. At each event, females lay about 30 eggs.

Babies appear as miniature versions of adults. Add plenty of plants to the tank before the shrimp give birth. Plants maximize survival rates, providing shrimp with plenty of hiding places and algae to eat.


Blue pearl shrimp are easy to care for. As long as you’re prepared to provide them with the basic aquarium conditions they need to survive, these creatures will do just fine.
