Neocaridina davidi (Red Cherry Shrimp / Fire Red Shrimp)

Overview

Red Cherry Shrimp (Neocaridina davidi) are arguably the most popular freshwater aquarium shrimp in the hobby. Known for their striking red coloration and incredible hardiness, these invertebrates are perfect for both novice and experienced aquarists. They act as a fantastic clean-up crew, constantly foraging for algae and detritus, bringing life and movement to the lower levels of the tank.

Distribution and Habitat

Originally, the wild type of Neocaridina davidi is found in the slow-moving streams and ponds of Taiwan. The vibrant red morphs, including the "Fire Red" and "Painted Fire Red" grades, were selectively bred in captivity for the aquarium trade and are not found naturally in the wild. In their natural habitat, they live among dense vegetation, leaf litter, and submerged wood.

Description of Red Cherry Shrimp

These dwarf shrimp typically reach about 1 to 1.5 inches in length. Females are generally larger and display a much deeper, more opaque red coloration, especially in higher grades like Fire Red or Painted Fire Red. Males are usually smaller and slightly more translucent. They feature a classic shrimp anatomy with a rostrum, long antennae, and a fan-like tail, making them fascinating to observe up close.

Keeping and Caring for Red Cherry Shrimp

Caring for these shrimp is incredibly straightforward, provided their basic needs are met. They are adaptable to a wide range of water conditions, making them ideal for beginners learning the ropes of invertebrate care. Stability is much more important than chasing exact water parameters.

Tank size:

A minimum of 5 gallons is recommended for a small colony, though a 10-gallon or larger tank provides more water stability and room for the population to grow and thrive.

Water Parameters:

While Red Cherry Shrimp are hardy, they still require a fully cycled tank and stable conditions to prevent molting issues and stress.

Temperature

They thrive comfortably between 65°F and 80°F (18°C - 27°C). Room temperature is often sufficient without a heater in warmer climates.

pH

A slightly acidic to alkaline pH of 6.5 to 8.0 is perfectly suitable for this species.

Hardness

They need minerals in the water for proper molting. Aim for a General Hardness (GH) of 4-8 dGH and a Carbonate Hardness (KH) of 3-15 dKH.

Ammonia, Nitrite, Nitrate

Ammonia and Nitrite must be strictly 0 ppm. Nitrates should be kept as low as possible, ideally under 20 ppm, through regular water changes and live plants.

Lighting

Standard aquarium lighting is fine. Lighting is more for the benefit of live plants and viewing the shrimp's vibrant colors than for the shrimp themselves.

Water flow

Gentle flow is preferred. Sponge filters are highly recommended as they provide excellent biological filtration, gentle aeration, and a safe grazing surface full of biofilm for shrimplets.

Decorations and Plants

Planted tanks are highly recommended. Mosses (like Java Moss), floating plants, and fine-leaved stem plants offer excellent hiding spots and surface area for biofilm to grow. Driftwood, almond leaves, and rocks also provide great natural decor and grazing spots.

Adding the Red Cherry Shrimp

Always use the drip acclimation method over 1 to 2 hours to slowly introduce them to the new water parameters and temperature. This gradual process prevents osmotic shock and ensures a smooth transition into your aquarium.

Some Feeding Tips

They are omnivorous scavengers. Supplement their natural biofilm and algae diet with high-quality shrimp pellets, blanched vegetables (like zucchini and spinach), and occasional protein-rich treats like frozen bloodworms. Remove any uneaten food after a few hours to prevent water fouling.

Dangers of Red Cherry Shrimp in the Planted Aquarium

Red Cherry Shrimp pose absolutely no danger to live plants; in fact, they help keep them clean by eating algae off the leaves. The real danger in the planted aquarium comes from external sources. Fertilizers containing high levels of copper, or pesticides hitchhiking on newly purchased plants, are highly toxic and can quickly wipe out a shrimp colony. Always quarantine and wash new plants carefully.

Tank mates & Compatibility

Keep them with small, peaceful nano fish like neon tetras, chili rasboras, or otocinclus catfish. Snails make excellent companions. Avoid large or aggressive fish like cichlids, goldfish, or bettas, which will likely view the shrimp as an expensive snack.

Breeding Red Cherry Shrimp

Breeding is incredibly easy. If you have both males and females in a stable, well-fed environment without predators, they will breed rapidly. Females will carry yellow or greenish eggs (becoming "berried") under their tails for about 3 to 4 weeks until fully formed, miniature shrimplets hatch. No special breeding tank is required if there is plenty of moss for the babies to hide in.

Conclusion

The Red Cherry Shrimp is a delightful, low-maintenance addition to the freshwater aquarium. Their bright red coloration, active personalities, and algae-eating habits make them a rewarding pet for any aquarist looking to explore the wonderful world of freshwater invertebrates.

Bloody Mary Shrimp (Neocaridina davidi)

Bloody Mary Shrimp are a selectively bred red color form of the freshwater Neocaridina davidi complex, valued for their deep, often opaque red coloration. They are small, peaceful scavengers suited to mature planted aquariums with stable chemistry and abundant biofilm. The trade name does not guarantee a formally distinct taxon, and exact lineage cannot be confirmed from the supplied images alone. They are generally manageable for beginners when water quality, acclimation, and mineral balance are handled carefully.
Black Sakura Shrimp

Black Sakura Shrimp is a selectively bred dark color form commonly sold under the Neocaridina davidi trade group. The name is commercial rather than a formal taxonomic rank, so exact lineage and grading may vary between suppliers. These small freshwater shrimp graze on biofilm, are generally peaceful, and can reproduce readily in a mature planted aquarium when water conditions are stable.
Amano Shrimp (Caridina multidentata)

The Amano shrimp is a translucent, algae-grazing freshwater shrimp valued for its peaceful behavior and persistent foraging. It is generally identified as Caridina multidentata, although image-based identification alone cannot confirm every specimen. Adults need mature, well-oxygenated aquariums with hiding places and stable water chemistry. Routine aquarium breeding is difficult because the larvae require brackish or marine conditions before returning to freshwater.
Amano Shrimp (Caridina multidentata)

The Amano shrimp is a translucent, adaptable freshwater algae grazer valued for its activity and peaceful behavior. It is usually identified as Caridina multidentata, formerly widely sold under the name Caridina japonica. Adults are larger and more robust than many ornamental dwarf shrimp, with dark brown to reddish speckles and markings. They suit mature planted aquariums, but successful reproduction requires a separate brackish larval stage, so a freshwater aquarium normally supports adults without producing surviving young.
Amano Shrimp (Caridina multidentata)

Amano shrimp are hardy freshwater algae grazers recognized by their translucent body, dark spotting and active scavenging behavior. They are widely used in planted aquariums, where they feed on algae, biofilm and uneaten food. Adults are generally peaceful and adaptable, but successful breeding is specialized: larvae require brackish water before juveniles can be acclimated to freshwater. The supplied trade label identifies these shrimp as Amano shrimp, although individual stock identity cannot be independently verified from the label alone.
Zebra Shrimp (Caridina cf. babaulti)

The Zebra Shrimp is a small freshwater Caridina sold under the name Caridina cf. babaulti, with a translucent body marked by dark transverse bands. The “cf.” designation indicates that the aquarium strain has not been confirmed as the exact species Caridina babaulti. It is a peaceful, algae-grazing shrimp suited to mature planted aquariums with stable, mineralized water. The pictured form shows pale body coloration with brown to black striping, but pattern intensity can vary with genetics, mood, diet, and background.
Red Rhinoceros Shrimp (Caridina gracilirostris)

Caridina gracilirostris is a small, translucent shrimp recognized by its elongated rostrum, often marked red or orange. It is associated with coastal freshwater, brackish and estuarine habitats, so aquarium care differs from that of fully freshwater Caridina species. Adults may be maintained in suitable freshwater or mildly brackish conditions, but successful reproduction involves free-swimming larvae and usually requires carefully managed brackish water. The supplied image appears consistent with this species, although image-based identification cannot confirm it with certainty.
Green Dwarf Shrimp (Caridina cf. babaulti)

The green dwarf shrimp sold as Caridina cf. babaulti is a small freshwater shrimp with variable green coloration and a peaceful, algae-grazing nature. The “cf.” designation indicates that the aquarium trade identification is provisional rather than a confirmed species-level determination. It suits mature, planted aquariums with stable, mineralized water, gentle filtration, plentiful biofilm, and no predatory tank mates.
Super Crystal Red Shrimp (Caridina logemanni)

Super Crystal Red Shrimp are a selectively bred red-and-white color form of Caridina logemanni, commonly kept in specialized freshwater aquaria. Their contrasting pattern, small size, and sensitivity to unstable conditions make them appealing but demanding shrimp. A mature, biologically established aquarium with soft, mineral-balanced water, gentle filtration, and abundant biofilm is important. The supplied source identifies these shrimp as Caridina logemanni; exact grade and lineage cannot be confirmed from the available material alone.
Snow White Bee Shrimp (Caridina logemanni)

The Snow White Bee Shrimp is a selectively bred freshwater form associated with Caridina logemanni, a small bee shrimp from the Caridina cantonensis group. It has a predominantly white, often translucent body and is valued for its appearance and breeding potential.

The supplied images show a pale white to cream animal with warm peach tones and reddish eyes; exact grade and lineage cannot be confirmed from images alone.
Royal Blue Tiger OE Shrimp (Caridina mariae)

The Royal Blue Tiger OE Shrimp is a selectively bred blue color form of Caridina mariae, commonly known as the tiger shrimp. “OE” refers to orange eyes, a visible trait in the supplied image. It is a small, peaceful freshwater shrimp suited to a mature, planted aquarium with stable, mineral-balanced water. Exact lineage and grade cannot be confirmed from the trade label and photograph alone.
Red Shadow Mosura Shrimp

Red Shadow Mosura is a selectively bred freshwater Caridina shrimp recognized for a deep red-and-white pattern and broad pale body markings. The trade name describes a color form rather than a formally established species, so it is best recorded as Caridina species or Caridina cf. cantonensis only when the breeder provides that identification. It suits mature, stable aquariums with soft, slightly acidic water, gentle filtration, biofilm, and careful maintenance. This specialized line is generally better for experienced shrimp keepers than for newly established tanks.
Golden Tiger Shrimp (Caridina cantonensis)

Golden Tiger Shrimp is a selectively bred Caridina cantonensis color form marked by a yellow to golden body and contrasting orange-red or darker tiger-like markings. The supplied image supports this general identification, but individual line names are not standardized and exact genetics cannot be confirmed from an image alone. It is a soft-water shrimp best kept in a mature, stable aquarium with gentle filtration, biofilm, suitable minerals, and peaceful tank mates.
Black Shadow Mosura Shrimp

Black Shadow Mosura is a selectively bred freshwater Caridina-type shrimp recognized by strong black-and-white patterning. The supplied label identifies it only as Caridina spec., so its exact species and line history cannot be confirmed from the available information. It is generally suited to mature, stable aquaria with soft, slightly acidic water, low mineral content, gentle filtration, and abundant biofilm. This is a specialist shrimp rather than a robust community species, and careful acclimation is important.
Sulawesi Yellow Ring Shrimp (Caridina spinata)

Caridina spinata is a Sulawesi freshwater shrimp known in the aquarium trade as the Yellow Ring Shrimp. It is associated with warm, alkaline, mineral-rich water and requires a mature, stable aquarium rather than soft, acidic conditions used for many other Caridina. The supplied source identifies this shrimp as C. spinata, although the accompanying images show a red-bodied, yellow-banded animal and cannot independently confirm species identity. Careful acclimation and consistent maintenance are central to long-term success.
Black Bee Shrimp (Caridina logemanni)

The Black Bee shrimp is a popular dwarf shrimp variety, scientifically recognized as Caridina logemanni. Prized for its striking high-contrast banding, this species is a staple in the hobby for advanced keepers. Originating from freshwater habitats in southern China, these shrimp require stable, specialized water conditions to thrive and successfully reproduce within a dedicated aquarium setup.
