Introduction
Aquarium enthusiasts often find themselves at a delightful crossroads when it comes to selecting inhabitants for their underwater worlds. Among the myriad of options, two popular choices are guppies and cherry shrimp. These aquatic creatures bring color, vivacity, and diversity to the aquarium, creating a harmonious balance between fish and invertebrates. However, a recurring question lingers: Will guppies eat cherry shrimp? In this exploration, we’ll delve into the appearances and behaviors of these captivating creatures to better understand the dynamics between them. Are guppies truly a threat to cherry shrimp, or can they coexist peacefully? Let’s embark on this underwater journey to find out.
About Guppies and Cherry Shrimp
Guppies
Appearance: Guppies (Poecilia reticulata) are small, colorful, and popular freshwater fish in the aquarium hobby. They are known for their vibrant and diverse color patterns, which can include shades of red, blue, green, yellow, and various combinations of these colors. Guppies are sexually dimorphic, meaning males and females have distinct differences in appearance:
- Males: Male guppies are typically more colorful and display striking patterns on their bodies. They have a slender body shape with an elongated dorsal fin and a colorful, fan-shaped tail fin known as a caudal fin.
- Females: Female guppies, on the other hand, are less colorful and often have a larger, rounder abdomen, especially when pregnant. Their fins are usually less flamboyant compared to the males.
Behavior: Guppies are known for their active and lively behavior. Here are some key characteristics of guppy behavior:
- Schooling Behavior: Guppies are social fish and tend to thrive when kept in groups. They often form schools, which not only provide social interaction but also safety in numbers.
- Constant Activity: Guppies are constantly on the move, exploring their surroundings and engaging in activities such as swimming, eating, and interacting with other fish.
- Breeding: Guppies are prolific breeders, with females giving birth to live fry (baby guppies). They can reproduce frequently, leading to a growing population if not controlled.
- Peaceful Nature: Guppies are generally peaceful fish and can coexist with a wide range of other community fish species. However, they may sometimes exhibit minor territorial behavior, especially among males.
Cherry Shrimp
Appearance: Cherry shrimp (Neocaridina davidi) are small, freshwater shrimp that have gained popularity in the aquarium hobby due to their striking red coloration. They are known for their bright red color, which can vary in intensity from pale to deep red. Some key features of cherry shrimp appearance include:
- Size: Cherry shrimp are quite small, typically growing to around 1 to 1.5 inches (2.5 to 3.8 cm) in length.
- Body Shape: They have a streamlined body with a somewhat translucent appearance. Their bodies are segmented, and they have a pair of long, slender antennae.
- Color Variations: While the most common form is bright red, selective breeding has also led to the development of other color variations, such as yellow, blue, and green.
Behavior: Cherry shrimp exhibit interesting and engaging behaviors within the aquarium:
- Foraging: Cherry shrimp are primarily herbivores and feed on algae, detritus, and microorganisms. They are diligent foragers and can help keep aquariums clean.
- Social Behavior: These shrimp are peaceful and typically exhibit social behavior within their own species. They often graze and explore together, making them a captivating addition to a community tank.
- Hiding: Cherry shrimp prefer having hiding places within the aquarium. They will often seek shelter in plants, rocks, or specially designed shrimp shelters.
- Breeding: Cherry shrimp are known for their ease of breeding in captivity. They give birth to miniature shrimp that look like miniature versions of the adults.
Both guppies and cherry shrimp are popular choices for community aquariums due to their captivating appearance and intriguing behavior. When kept in suitable conditions and provided with appropriate care, they can thrive and coexist harmoniously, adding beauty and activity to your tank.
Will Guppies Eat Cherry Shrimp?
So, will guppies eat cherry shrimp? Guppies are generally considered peaceful fish, but they can be opportunistic and may eat small, slow-moving organisms like cherry shrimp fry, particularly if they are hungry or if the shrimp fry are very small. Guppies have small mouths and may see small shrimp fry as potential food. However, whether or not guppies will actively hunt and eat cherry shrimp fry depends on several factors, including the availability of other food sources and the individual behavior of the guppies.
It’s important to remember that individual fish and shrimp can have varying temperaments, and while some guppies may ignore cherry shrimp, others may be more inclined to see them as a potential food source. Therefore, the success of keeping these two species together will depend on careful observation and appropriate tank management.

Aquarium Setup
Setting up a tank to accommodate both guppies and cherry shrimp can be a rewarding and visually appealing endeavor. Here are some steps to create an environment that suits both species while providing hiding spaces for the shrimp:
- Select the Right Tank: A tank of at least 10-20 gallons (40-80 liters) is a good starting point, as it offers enough space for both guppies and cherry shrimp. A larger tank is generally better, as it allows for more hiding places and water stability.
- Aquascape with Plants: Live aquatic plants serve a dual purpose. They provide hiding spots for cherry shrimp and guppy fry, and they also improve water quality. You can choose plants such as Java moss, Java fern, Anubias, and various carpeting plants.
- Substrate: Use a fine-grained substrate like sand or small gravel. This is gentler on the shrimp and helps create a natural look. You can also incorporate small pieces of driftwood and rocks for additional hiding spots.
- Shrimp Shelters: You can add specialized shrimp shelters or caves that provide secure hiding spaces. These are often made from ceramic or PVC and come in various shapes and sizes.
- Adequate Filtration: Use a gentle sponge filter or a pre-filter sponge on the filter intake to prevent shrimp and guppy fry from getting sucked into the filter.
- Water Parameters: Guppies and cherry shrimp thrive in similar water conditions. Aim for a temperature between 72-78°F (22-26°C) and a pH level around 7.0. Regular water changes are essential to maintain water quality.
- Proper Lighting: Provide moderate lighting to support plant growth and create a natural environment. Consider using a timer to establish a consistent light cycle.
- Feed Appropriately: Offer a varied diet to both guppies and cherry shrimp. Guppies can be fed with high-quality guppy flakes or pellets, while cherry shrimp eat detritus, algae, and microorganisms. Occasionally, supplement their diet with blanched vegetables like zucchini or spinach for the shrimp.
- Monitor Behavior: Keep a close eye on the tank’s inhabitants to ensure everyone is getting along. If you notice any aggression or predation, consider removing the offending guppies or providing additional hiding places for the shrimp.
- Population Control: Guppies are known for their breeding capacity. If you don’t want an overpopulation of guppy fry, you may need to isolate pregnant guppies in a breeding box or a separate tank.
- Maintain Water Quality: Regular water testing and maintenance are crucial. Perform water changes as needed to keep water parameters stable and ensure the health of both guppies and shrimp.
By setting up your tank with these considerations, you can create a harmonious environment for guppies and cherry shrimp, providing hiding spaces for the shrimp while enjoying the beauty of both species coexisting.
Conclusion
In the intricate realm of aquarium keeping, the compatibility of guppies and cherry shrimp remains a topic of fascination. The question, “will guppies eat cherry shrimp?”, echoes throughout the community, yet the answer lies in the intricacies of tank setup, observation, and thoughtful management. As we’ve discovered, guppies, with their kaleidoscopic beauty and dynamic behavior, often coexist peacefully with cherry shrimp, especially when provided with ample hiding spaces and suitable care. Through a carefully orchestrated aquatic environment, these two species can thrive side by side, offering aquarists a glimpse into the delicate balance of nature’s wonders within the confines of a glass box. So, to the curious aquarist pondering this perennial question, the answer is not absolute but a journey of exploration and understanding in the enchanting world of underwater life.
