5 Common Reasons Shrimps Die and How to Prevent It

Incorrect Water Parameters:
One of the most common mistakes beginners make is not researching the specific water parameters that different shrimp species require. Different shrimp species have varying preferences for water conditions.

For example, Caridina shrimp prefer soft, acidic water with a low pH, while Neocaridina shrimp thrive in harder water with a higher pH. It's crucial to do your research and ensure your tank's water parameters match your shrimp's needs to prevent their demise.

High Temperatures:
Shrimp are highly sensitive to high temperatures. Caridina shrimp, in particular, are vulnerable to elevated temperatures. In between 20 and 22 degrees Celsius is the ideal temperature. Temperature above 25 degrees Celsius may harm the shrimps but Neocaridina shrimp can tolerate up to 29 degrees Celsius.

To protect your shrimp, monitor your tank's temperature, especially during hot weather, and consider investing in an aquarium chiller or using fans to maintain a suitable temperature range.

Rapid Changes in Water Parameters:
Shrimp are highly sensitive to sudden fluctuations in water parameters or temperature. When performing water changes, ensure that you do it slowly, allowing the new water to acclimate to the existing tank conditions.

Drip acclimating your shrimp is a safe way to introduce them to new water. By maintaining stable water conditions, you can reduce stress and prevent shrimp deaths.

Toxic Substrate:
Surprisingly, toxic substrate is a common, often overlooked reason why shrimp may die in your aquarium. Over time, organic matter, uneaten food, and shrimp waste can accumulate in the substrate, creating a toxic environment for your shrimp. These toxins can poison your shrimp and lead to their demise.

To prevent this, avoid disturbing the substrate excessively, and consider using feeding dishes to minimize food reaching the substrate. Creating feeding areas with a thin layer of substrate can also help prevent toxic buildups.

Bacterial Infections:
Bacterial infections are perhaps the most severe threat to a shrimp colony. They can quickly wipe out your entire population in a matter of weeks. Symptoms of bacterial infections include weakened and inactive shrimp, reduced feeding activity, and an increase in shrimp deaths.

If you suspect a bacterial infection, the best course of action is quarantine, but it may not always guarantee success. Prevention is key; maintain strict hygiene, wash your hands before interacting with your tank, and sterilize new decorations or plants before introducing them to your aquarium.


Shrimp keeping is a rewarding hobby, but it requires careful attention to detail to ensure your shrimp thrive in their aquatic environment. By understanding and addressing the common reasons why shrimp die, you can significantly improve your success as an aquarist. Keep your water parameters in check, manage temperature fluctuations, maintain a clean tank environment, and be vigilant about bacterial infections to ensure a healthy and thriving shrimp colony. Good luck, and enjoy the beauty of these fascinating aquatic creatures!
