Orange Fire Shrimp

24 October 2026

Orange Fire Shrimp is a selectively bred orange color form of the freshwater dwarf shrimp commonly identified in the aquarium trade as Neocaridina davidi. The supplied trade label does not provide a verified scientific identification, so this article treats the shrimp as likely N. davidi rather than a confirmed specimen-level determination. It is a peaceful algae grazer and scavenger suited to mature planted aquariums with stable, mineral-rich water and careful protection from predatory tank mates.

Identification and taxonomy

Orange Fire is a trade name for an orange selective-breeding line, not a separate species. It is generally associated with Neocaridina davidi, family Atyidae, order Decapoda, but the supplied label and images do not establish a definitive scientific identification. Color intensity may range from pale yellow-orange to saturated orange, and offspring from lower-grade lines can show reduced or variable coloration.

Natural habitat

Neocaridina davidi is a freshwater shrimp associated with shallow streams, pools and vegetated margins in East Asia. Its natural environments provide hard surfaces, biofilm, leaf litter, cover and gentle to moderate water movement. In an aquarium, mosses, fine plants, wood and other textured surfaces help reproduce these feeding and shelter opportunities.

Aquarium and water parameters

Use a fully cycled aquarium with ammonia and nitrite at zero and low nitrate. A temperature of 18–26 °C, pH 6.5–8.0, moderate hardness and reliable calcium and magnesium availability are suitable general targets. Stability is more important than chasing an exact value. Avoid sudden changes in temperature, pH, total dissolved solids or mineral content, and use a gentle sponge or protected intake.

Feeding

These shrimp graze continuously on biofilm, algae and microorganisms growing on plants, wood and hard surfaces. Offer small amounts of a quality shrimp food, algae-based food or blanched vegetables once or several times weekly according to colony size. Remove uneaten food promptly. Leaf litter from suitable pesticide-free leaves can provide cover and a slowly consumed food source. Avoid overfeeding, which can degrade water quality.

Tank mates

The safest companions are other peaceful dwarf shrimp and small, non-predatory snails. Many fish will eat shrimplets, and larger, boisterous or predatory species may injure adults. If keeping fish, choose very small peaceful species and provide dense moss, fine-leaved plants and other refuge, while accepting that juvenile survival may be lower. Do not mix different Neocaridina color lines if maintaining a predictable orange breeding line matters.

Molting and health

Shrimp periodically shed their exoskeleton as they grow. A freshly molted shrimp is vulnerable, so caves, plants, wood and leaf litter are important refuges. Leave a shed exoskeleton in the aquarium because the colony may consume it and recover minerals. Failed molts are commonly associated with instability, unsuitable hardness, poor nutrition or sudden changes; do not add unverified mineral products without testing and a clear need.

Breeding

In a stable mature aquarium, breeding is usually straightforward. After mating, the female carries fertilized eggs beneath the abdomen and regularly fans them until fully formed young hatch. The young are miniature shrimp and do not require a separate larval stage or saltwater. Provide abundant biofilm and fine cover, avoid strong filter intakes and make only gradual water changes. Orange offspring may vary in shade and quality, so selective culling is used to strengthen the color line.

Orange Rili Shrimp

Orange Rili Shrimp are a selectively bred color form of the freshwater dwarf shrimp commonly sold as Neocaridina davidi. Their translucent body is interrupted by orange patches, often concentrated on the head, abdomen, and tail. They are peaceful, adaptable scavengers suited to mature planted aquariums. Because trade names can be applied inconsistently, exact lineage and grading may vary, but the pictured shrimp are consistent with an Orange Rili Neocaridina form.
Neon Yellow Fire Shrimp

Neon Yellow Fire Shrimp are selectively bred freshwater dwarf shrimp recognized for their strong yellow to golden coloration. The supplied images are consistent with a yellow Neocaridina-type shrimp, commonly traded as Neocaridina davidi, although exact strain and species cannot be confirmed from photographs or the source label alone. They are peaceful algae grazers suited to mature, planted aquariums with stable water chemistry and gentle filtration.
Green Jade Shrimp

Green Jade Shrimp are a selectively bred green color form commonly associated with Neocaridina davidi, a small freshwater dwarf shrimp. Their exact line and taxonomic identity cannot be confirmed from the supplied trade label or images alone. They are generally peaceful, adaptable aquarium animals that graze on biofilm and accept prepared foods. Stable, mature aquarium conditions, mineral availability, and protection from predatory tank mates are more important than chasing narrowly defined water values.
Carbon Rili Shrimp

Carbon Rili Shrimp are selectively bred freshwater dwarf shrimp recognized by contrasting dark and translucent body sections, often with blue or pale areas and small dark markings. The trade name describes a color pattern rather than a formally defined species or taxonomic rank. They are commonly treated as a Caridina cantonensis complex form, but exact parentage can vary between lines. Stable, clean water, mature biofilm and gentle tank mates are central to long-term care and successful breeding.
Blue Black Rili Shrimp

Blue Black Rili Shrimp are a selectively bred color form of the freshwater dwarf shrimp commonly identified as Neocaridina davidi. They combine dark blue to black body sections with translucent or blue-clear areas, creating an irregular rili pattern. The trade name is not a formal taxonomic designation, and strain quality can vary, so exact lineage should be confirmed with the breeder or seller. They are peaceful, adaptable scavengers suited to mature planted aquariums.
Blue Jelly Shrimp

Blue Jelly Shrimp are a selectively bred blue color form of the freshwater Neocaridina davidi species, commonly kept in planted community aquariums. Their translucent blue bodies can vary in intensity, and some individuals show clear areas or darker blue markings. The supplied images are consistent with this trade name, but color names are not formal taxonomic classifications. They are peaceful, adaptable scavengers that reproduce readily when water quality, shelter, and mineral availability are stable.
Blue Dream Shrimp (Neocaridina davidi)

Blue Dream Shrimp are a selectively bred blue color form of the freshwater species Neocaridina davidi. The supplied images show intensely blue individuals in a planted aquarium, but photographs alone cannot confirm a particular commercial grade or lineage. They are generally peaceful, adaptable dwarf shrimp that graze on biofilm and benefit from stable, mature aquarium conditions. A planted tank with gentle filtration, shelter, and mineral-rich water supports feeding, successful molts, and colony growth.
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.
