Cherry shrimp are known for their bright red coloration and active behavior. However, if you notice yours isn’t moving or appears lethargic, it can be concerning.

There could be various reasons for cherry shrimp not moving, including poor water parameters, water quality, disease, molting, or old age.

In this article, we’ll explore the different factors that could cause your cherry shrimp to become inactive and discuss ways to address the issue.

Why Is My Cherry Shrimp Staying Still?

Staying still can be a sign of underlying issues that you need to address.

Take a look at these five potential causes in detail. We’ll also provide practical solutions to help your cherry shrimp become more active and healthier.

1 – Poor Water Quality

Poor water quality can be a significant factor in causing shrimp to become inactive. It can lead to high levels of toxic substances such as ammonia and nitrate, which can be harmful to shrimp.


To fix or avoid this, ensure you’re performing regular water changes, cleaning the aquarium, and using a good filtration system.

2 – Suboptimal Water Parameters

Cherry shrimps are sensitive to changes in water parameters, including temperature, pH, and hardness. If the water isn’t within the optimal range, it can cause stress and make the shrimp less active.


It’s essential to maintain stable and consistent water conditions to keep the shrimp healthy and active.

Hence, monitor the water parameters regularly using a reliable water testing kit. Then, make necessary adjustments to help ensure optimal water conditions for cherry shrimp.

It’s also important to acclimate new shrimp to the aquarium’s water parameters slowly to avoid any shock or stress.

3 – Disease

Cherry shrimp can be prone to diseases and parasites.

This can cause them to become lethargic and not move. Shrimp diseases are due to bacterial, fungal, or parasitic infections.

It can be challenging to detect the disease, as the symptoms may not be apparent until it has progressed.

Here are the common symptoms of disease in cherry shrimp:

  • Inactivity
  • Loss of appetite
  • Discoloration
  • Erratic swimming patterns


If left untreated, the disease can spread quickly to the shrimps in the aquarium. This leads to an outbreak and potential loss of the entire shrimp colony.

Therefore, if you suspect your cherry shrimp is infected, quarantine the affected shrimp immediately. Then consult a veterinarian or an experienced aquarium hobbyist to get help.

Generally, treatments may include medications, water changes, and adjustments to water parameters.

4 – Molting

Shrimps shed their exoskeleton as they grow.

This process, called molting, can cause them to become less active and hide until their new exoskeleton hardens. Its frequency depends on age, diet, and water quality.

However, molting can also be a sign of stress or poor water conditions. If the water parameters aren’t optimal or consistent, it can cause stress and affect the shrimp’s ability to molt successfully.


Ensure successful molting by maintaining stable water conditions and providing a balanced and nutritious diet. Additionally, it’s crucial to provide hiding places and secure locations in the aquarium where the shrimp can molt without disturbance.

Providing a stress-free environment is crucial for the shrimp’s overall health and activity levels as well.

5 – Old Age

Cherry shrimps have a lifespan of no more than 2 years. As they age, they may become less active, lose their coloration, and develop health issues.


There may not be much you can do if your shrimp is nearing the end of its life. However, there are some ways to prolong their lifespan and keep them healthy for as long as possible.

Provide optimal water conditions, a balanced and nutritious diet, and a stress-free environment. These can help maintain the shrimp’s overall health and activity levels.

Additionally, prompt treatment of any health issues can help prolong the shrimp’s lifespan and keep them active longer.

Do Cherry Shrimp Play Dead?

Cherry shrimps don’t play dead in the same way that some animals do. However, they may sometimes appear motionless or inactive.

If your cherry shrimp appears motionless, it’s essential to observe it closely to determine whether it’s alive or dead.

How to Tell If a Cherry Shrimp is Alive or Dead?

If you’re unsure whether a cherry shrimp is alive or dead, you can gently touch it with a tool to see if it responds. If it doesn’t move or react, it’s likely dead.

It’s important to remove dead shrimp from the tank as soon as possible to prevent them from decomposing. If you fail to do so, it may affect the water quality.

What Are the Signs of a Stressed Cherry Shrimp?

Stressed cherry shrimp may exhibit several signs. These include hiding, reduced activity levels, loss of color, and slow movement. Identifying these signs can help you take action to address the underlying cause and prevent further issues.

How to Provide a Stress-Free Environment to Cherry Shrimps?

Cherry shrimps need a stress-free environment. Stress can lead to health problems, including decreased appetite, weakened immune system, and increased susceptibility to disease.

Here are some ways to provide a stress-free environment for your shrimps:

  • Maintain stable water parameters
  • Provide hiding places
  • Don’t overcrowd
  • Use a gentle filtration system
  • Avoid sudden changes in the environment
  • Make sure not to pick aggressive tank mates

Final Thoughts

Identifying the causes of cherry shrimp not moving, along with the solutions, is essential for every shrimp owner.

By taking a proactive approach to your shrimps’ health and well-being, you can ensure these fascinating creatures can thrive in their environment.
