As their name suggests, they possess a vibrant red coloration, which contrasts beautifully against their transparent bodies. One of the most characteristic features of Red Rili Shrimp is their unique pattern, with red coloration concentrated on their head, tail, and abdominal segment, while their midsection remains translucent.

Tank Setup

Creating a suitable tank setup is vital to provide Red Rili Shrimp with an environment that resembles their natural habitat and encourages their well-being. Here are some essential aspects to consider when setting up a tank for your Red Rili Shrimp:

Tank Size

A small aquarium with a minimum capacity of 5 gallons (19 liters) is suitable for a small group of Red Rili Shrimp. However, for optimal comfort and enjoyment, a larger tank with a capacity of 10 gallons (38 liters) or more is recommended.


Choose a fine-grained substrate like sand or gravel to create a natural-looking setting for your shrimp. Avoid using sharp or coarse substrate that could potentially harm their delicate bodies.

Plants and Decorations

Provide ample hiding spots and plant cover using live or artificial plants, driftwood, and rocks. These features not only mimic the natural habitat of Red Rili Shrimp but also offer them places to explore, graze, and take shelter.

Filtration and Aeration

Install a gentle filtration system, like a sponge filter, to maintain water quality without creating strong currents that can hinder Red Rili Shrimp’s movement. Aeration through an air pump is also beneficial as it boosts oxygen levels, ensuring a healthy environment for your shrimp.

Remember to cycle your tank before introducing Red Rili Shrimp, allowing beneficial bacteria to establish, and regularly test water parameters to ensure the conditions remain stable and optimal for your shrimp.


Feeding Red Rili Shrimp is a straightforward process, as these delightful creatures are omnivores with a hearty appetite. They will readily consume a variety of food sources, including:

  1. Prepared Food: High-quality shrimp pellets, flakes, or granules specifically formulated for shrimp can form the staple diet of your Red Rili Shrimp. These commercially available foods are enriched with essential nutrients and minerals, promoting their overall health.
  2. Vegetables: Supplement their diet with blanched leafy greens, such as spinach, kale, or lettuce. These vegetable treats provide necessary fiber and additional nutrients.
  3. Protein: Offer your Red Rili Shrimp occasional protein-rich treats like small amounts of thawed, peeled, and crushed peas, brine shrimp, or bloodworms. These protein sources provide variety and ensure well-rounded nutrition.

Feed your shrimp small amounts of food once or twice a day, ensuring they consume it within a few minutes. Overfeeding can lead to water quality issues, so it’s essential to strike a balance between offering enough food for their needs without creating excess waste.


Red Rili Shrimp are prolific breeders, making them an ideal choice for those interested in observing their shrimp colony grow. Breeding Red Rili Shrimp can be a rewarding experience, as long as you provide the right conditions and pay attention to a few essential factors:

Gender Identification

Red Rili Shrimp exhibit sexual dimorphism, with females typically being larger and displaying a more vibrant red coloration than males. Females also have a saddle-shaped marking on their backs, which indicates their reproductive readiness.

Reproductive Strategy

Red Rili Shrimp are relatively easy to breed, as they are adept at reproducing in freshwater aquariums. Females carry fertilized eggs under their tails until they hatch into miniature shrimp. Providing suitable hiding spots, planting areas, and other habitat enhancements will encourage successful breeding.

Optimal Breeding Conditions

Maintain stable water parameters within the recommended ranges mentioned earlier, ensuring good water quality. Adequate nutrition and varied diet play a crucial role in supporting the breeding process.

Keep in mind that Red Rili Shrimp readily interbreed with other Neocaridina davidi color variations, so you might observe offspring with mixed colorations. These mixed-color shrimp can be fascinating to observe and can add diversity to your shrimp colony.


Red Rili Shrimp are known to be peaceful and non-aggressive towards other tank inhabitants. When considering tankmates for your Red Rili Shrimp, choose species that can coexist harmoniously in a community setup. Here are some compatible tankmates for Red Rili Shrimp:

Small Fish

Peaceful and non-predatory fish species like dwarf rasboras, celestial pearl danios, and endlers can be suitable tankmates. Avoid larger or aggressive fish that may pose a threat to your shrimp.


Adding small snail species, such as nerite or Malaysian trumpet snails, can be beneficial for your tank. They help maintain the tank’s cleanliness by consuming algae and decaying matter.

Other Shrimp

Red Rili Shrimp can coexist peacefully with other dwarf shrimp species, like Cherry Shrimp or Blue Velvet Shrimp, as long as they share similar water parameters.

Remember that not all tankmates are compatible with Red Rili Shrimp. Always research and consider the specific compatibility requirements of the species you intend to introduce to ensure a harmonious and stress-free environment for all inhabitants.

Common Health Issues

While Red Rili Shrimp are generally hardy and resistant to many diseases, providing optimal care can prevent common health issues. Some potential health concerns to be aware of include:

Poor Water Quality

Inconsistent or poor water quality can lead to stress, weakened immune systems, and bacterial infections in Red Rili Shrimp. Regular water testing and maintenance, along with proper filtration, can help prevent these issues.

Molting Issues

Shrimp periodically shed their old exoskeletons to grow. Molting problems can occur if the water parameters are unfavorable or if the shrimp lack essential minerals for the molting process. Providing a calcium-rich diet and stable water conditions can mitigate these risks.
