Introduction to controlling cherry shrimp population.
Cherry shrimp population control (Neocaridina davidi) is an essential aspect of maintaining a healthy and balanced aquatic ecosystem in your aquarium.
These brightly colored, freshwater invertebrates are popular among hobbyists for their ornamental appeal and their ability to consume algae and debris, thus keeping the tank clean.
However, due to their prolific breeding nature, the cherry shrimp population can quickly spiral out of control, leading to overcrowding, depleted resources, and potential harm to the overall tank environment.
In this guide, we will explore effective methods to manage the population growth of cherry shrimp, ensuring that you can enjoy the visual spectacle they provide while maintaining a harmonious and sustainable aquatic habitat.

How to control cherry shrimp population by reducing the feeding
Reducing the amount of food you provide to your cherry shrimp can have a significant impact on their reproduction rate.
Overfeeding can lead to higher breeding rates, as the shrimp have more energy and resources available for reproduction.
To control their population, try cutting back on the amount of food you offer, and provide only enough for them to maintain their health. Monitor the shrimp carefully to ensure they receive adequate nutrition, without overfeeding them.
I use the two hour rule as an example of how you should feed your shrimp, simply place the food in a dish and leave it for 2 hours if there is food left remove it, this not only stops over population it stops the food going off and polluting the tank.
Control water parameters
Maintaining optimal water conditions is essential for the health and well-being of your shrimp. However, if you want to control their population growth, you can make slight adjustments to water parameters, such as temperature and pH, to discourage breeding.
For instance, lowering the water temperature slightly or maintaining a slightly higher pH level can slow down reproduction rates. Be cautious with these changes, as drastic fluctuations can stress or harm the shrimp.
The optimal breeding temperature for cherry shrimp is around 24c so if your home is on the cooler side you could remove the heater
from the tank as a form of population control.
Remove females
Gravid females are those carrying eggs in their swimmerets. By identifying and removing these females from the main tank, you can prevent a new generation of shrimp from being born.
This method requires close monitoring and can be time-consuming, but it is an effective way to control the population without introducing predators or making drastic environmental changes.
Remember if you choose this method of controlling your cherry shrimp population please consider adding the females to a cull tank.
Add predators
Introducing natural predators, such as small fish species, into your tank can help control the cherry shrimp population. Species like dwarf gouramis, bettas, and small tetras can prey on the shrimp, especially the juveniles, keeping the population in check.
Be aware that adding predators may also lead to a decline in the shrimp population, so ensure that the predator-prey balance is maintained.
Separate males and females
Separating males and females is a highly effective method for controlling cherry shrimp breeding, as well as for other prolific livebearing species such as guppies and endlers.
By placing males and females in different tanks, you can prevent mating and the subsequent production of offspring, making it easier to manage the population within your aquarium.
Identifying the gender of cherry shrimp can be challenging, particularly for younger shrimp. However, with practice and careful observation, you can distinguish them based on coloration and body shape.
Males are typically smaller and less colorful than females, while females have a more rounded, curved underbelly to accommodate eggs. Gravid females can be identified by the presence of eggs in their swimmerets, which appear as small, greenish-yellow spheres.
This method of population control is also popular among breeders of livebearing fish species, such as guppies and endlers.
These fish are known for their rapid breeding rates and can quickly overcrowd a tank if not managed properly. By separating males and females, breeders can control when mating occurs and regulate the population growth within their tanks.
By employing the technique of separating males and females, you can effectively manage the population of cherry shrimp and other livebearing species in your aquarium, ensuring a balanced and healthy environment for all inhabitants.
Limit tank space
Cherry shrimp are more likely to breed in larger, more spacious tanks. By limiting the size of their habitat, you can help discourage excessive breeding. However, be careful not to overcrowd the tank, as this can lead to stress and poor water quality, which can adversely affect the health of your shrimp.
Remove excess plants
This one sounds ridiculous but if your a mass breeder of shrimp you know this to be true, all of my tanks that are stuffed full of neocaridina have billions of baby shrimplets and plants.
Cherry shrimp thrive in densely planted tanks, as they provide hiding spots and breeding grounds. By removing some plants and decorations from your tank, you can reduce the number of available hiding places, making it more challenging for the shrimp to breed.
This method can help slow down population growth while maintaining the aesthetic appeal of your aquarium.
Culling
Culling involves selectively removing shrimp from the tank based on specific criteria such as size, color, or health. This method can help control the population by eliminating weaker or undesirable individuals, ensuring that only the healthiest and most vibrant shrimp remain in your tank.
Culling requires a careful and ethical approach, and removed shrimp can be relocated to other tanks, given away, or traded with other hobbyists.
I personally do not kill my shrimp when it comes to culling I have a separate tank that all my culls can go into, ethically the only type of shrimp that you should consider culling as in killing is a deformed shrimp that you do not want to pass on it genetics.
Start Selling Your Cherry Shrimp
Another effective method for controlling the cherry shrimp population in your aquarium is by selling the excess shrimp. This not only helps manage the number of shrimp in your tank but also provides a potential source of income or trade for other aquarium-related items.
In this section, we will discuss the necessary steps and materials needed to start selling your cherry shrimp.
1. Prepare for shipping
To successfully sell and ship your cherry shrimp, you’ll need to acquire specific materials to ensure the shrimp arrive safely and in good health. These materials include:
- Breather bags: Unlike regular plastic bags, breather bags allow the exchange of gases, ensuring your shrimp have enough oxygen during transportation. These bags also help reduce the risk of leaks.
- Rubber bands or bag clips: Use rubber bands or bag clips to securely seal the breather bags, preventing any water from escaping or contaminants from entering.
- Styrofoam boxes or insulated shipping containers: To maintain a stable temperature during shipping, use Styrofoam boxes or insulated containers. These materials will provide insulation, protecting your shrimp from extreme temperature fluctuations.
- Packing material: Use packing materials such as paper, bubble wrap, or foam peanuts to fill any empty spaces in the shipping box, providing additional insulation and preventing the breather bags from moving during transit.
2. Advertise your shrimp for sale
To find potential buyers, you can advertise your cherry shrimp online or in local markets and groups. Some popular platforms for selling shrimp include:
- Aquarium forums and groups: Many online aquarium communities have dedicated sections for buying, selling, or trading aquatic livestock. Join these forums and groups to connect with fellow hobbyists and advertise your shrimp.
- Social media: Use social media platforms like Facebook, Instagram, and Twitter to promote your shrimp. Create a dedicated account or join local aquarium groups to reach a wider audience.
- Online marketplaces: Websites like eBay, Aquabid, or local classifieds websites can be excellent platforms for selling your cherry shrimp. Make sure to include clear photos and detailed descriptions to attract potential buyers.
- Local fish stores or aquarium clubs: Reach out to local fish stores or aquarium clubs to inquire about selling or trading your cherry shrimp. These establishments may be interested in buying your shrimp or can provide valuable connections with other hobbyists.
3. Ship your shrimp
Once you have found a buyer and agreed on the price and shipping method, it’s time to prepare your shrimp for shipping. Follow these steps for a successful shipment:
- Fast your shrimp for 24 hours before shipping to reduce waste production in the breather bags.
- Fill the breather bags with tank water and gently add the shrimp. Make sure not to overfill the bags or overcrowd the shrimp.
- Seal the bags securely with rubber bands or bag clips, ensuring that there are no leaks.
- Place the sealed bags inside the insulated shipping container and fill any empty spaces with packing material to prevent movement during transit.
- Seal the shipping container and attach the appropriate shipping labels, including a “Live Fish” or “Fragile” label if necessary.
- Ship your shrimp using a reliable shipping service, preferably with tracking and fast delivery options, to ensure the shrimp arrive safely and in good health.
By selling your cherry shrimp, you can effectively control their population while sharing the joy of these beautiful creatures with other hobbyists. This approach also promotes responsible shrimp keeping and helps maintain a healthy and balanced aquatic environment.
