363

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.

Taxonomy and identification

Blue Dream is a selectively bred ornamental color form, not a separate species. It is generally traded as Neocaridina davidi, a freshwater shrimp in the family Atyidae. The exact strain, grade, and breeding history cannot be confirmed from the supplied source label or images alone. Visible specimens range from vivid blue to very dark blue, with some variation in opacity and coverage.

Natural habitat

Neocaridina davidi is associated with freshwater habitats in East Asia, including streams, ponds, and slow-moving waters. In aquaria, it uses plants, wood, rocks, and other surfaces for grazing and shelter. Dense vegetation and fine-leaved plants provide biofilm as well as refuge for juveniles.

Aquarium and water parameters

Use a fully cycled, mature aquarium with stable water chemistry and gentle flow. A sponge filter or a protected intake is useful because it reduces the risk of injury and prevents young shrimp from being drawn into the filter. A practical range is 18–26 °C and pH 6.5–8.0. Maintain ammonia and nitrite at zero, avoid abrupt changes, and keep nitrate low. Provide calcium and other minerals through appropriately mineralized water and a suitable diet; do not make large, rapid corrections to hardness or pH.

Feeding

These shrimp continually graze on algae, microorganisms, and biofilm growing on aquarium surfaces. Offer small amounts of a quality shrimp food, with occasional blanched vegetables or other suitable foods. Remove uneaten food promptly, especially in small aquaria. Feeding should be lighter when natural grazing is abundant. A varied diet containing minerals and adequate protein supports growth, reproduction, and recovery after molting.

Tank mates

The safest companions are other peaceful Neocaridina shrimp and small, non-predatory invertebrates such as many freshwater snails. Fish may eat shrimplets, even when they do not harm adults. Avoid large, predatory, or highly active fish, crayfish, and aggressive invertebrates. If preserving the blue color form is important, do not mix it with other Neocaridina color lines, because crossbreeding can produce less predictable colors in later generations.

Molting and care

Shrimp periodically shed their exoskeleton to grow. Before molting, an individual may become less active or hide; after shedding, it is soft and especially vulnerable. Provide cover such as moss, dense plants, and small crevices, and avoid disturbing or handling the shrimp. Do not remove a normal shed exoskeleton immediately, because shrimp commonly consume it and reclaim minerals. Persistent failed molts are often linked to unstable water, unsuitable mineral content, poor nutrition, or sudden changes.

Breeding

Neocaridina davidi is a freshwater-breeding shrimp with direct development. Once mature, females carry fertilized eggs beneath the abdomen and fan them until fully formed miniature shrimp hatch. Stable conditions, abundant biofilm, and dense plant cover improve survival. Keep filtration intake covered and avoid large water changes or chemical treatments during a berried female’s development. Young shrimp resemble small versions of adults and can remain in the same aquarium when tank mates are non-predatory.

Amano Shrimp (Caridina multidentata)

The Amano shrimp, Caridina multidentata, is a peaceful freshwater aquarium shrimp recognized by its translucent body and reddish-brown speckles. It is a useful grazer of algae and biofilm, but it requires stable, mature water and secure tank cover. Adults are generally hardy, while successful reproduction is challenging because the larvae require brackish conditions before completing development in freshwater.
Bee Shrimp Wild Form (Caridina logemanii var.)

The bee shrimp wild form is a small, soft-water Caridina with a translucent body marked by irregular black and pale bands or patches. Aquarium specimens are commonly associated with the Caridina logemanni lineage, although the supplied “var.” label does not establish a formally recognized taxonomic rank or exact collection locality. It is best kept in a mature, stable aquarium with cool, acidic, mineral-poor water, abundant biofilm, gentle filtration and peaceful tank mates. Stable conditions are more important than pursuing narrowly precise figures.
Amano Shrimp (Caridina multidentata) Care Guide

Amano shrimp, Caridina multidentata, are transparent to grayish freshwater shrimp marked with small brown or reddish spots and dashes. Also sold as Yamato shrimp, they are peaceful scavengers that graze on algae, biofilm and leftover foods. They suit mature community aquariums with stable, well-oxygenated water. Adults live in freshwater, but successful reproduction requires raising their drifting larvae in brackish water, so a self-sustaining freshwater colony is uncommon.
Amano Shrimp (Caridina multidentata)

The Amano Shrimp, Caridina multidentata, is a translucent freshwater shrimp valued for grazing algae and biofilm. It is generally peaceful, adaptable and suitable for planted community aquariums with stable, clean water. Adults live in freshwater, but successful reproduction requires a separate brackish or marine larval stage, so routine captive breeding is substantially more demanding than everyday care. The supplied images are consistent with this species, although color and pattern vary among individuals.
Amano Shrimp (Caridina multidentata)

The Amano Shrimp, Caridina multidentata, is a transparent to grayish freshwater shrimp marked with brown or reddish-brown spots and dashes. It is valued for grazing on algae and biofilm, but it is not a fully freshwater-breeding species: its larvae require brackish or marine conditions. Stable water, mature surfaces, shelter, and peaceful tank mates are important for long-term care.
Amano Shrimp (Caridina multidentata)

The Amano shrimp is a transparent, spotted freshwater shrimp formerly widely sold as Caridina japonica and now generally identified as Caridina multidentata. It is valued for grazing algae and biofilm without usually harming healthy plants. Adults are peaceful and hardy when water quality is stable, but successful breeding requires brackish or marine conditions for the larval stage. The supplied images show the typical translucent greenish-brown, dark-spotted appearance.
Algae-Eating Shrimp Set: Likely Amano Shrimp

This aquarium-library entry concerns a group of algae-grazing shrimp that appear to be Amano shrimp, Caridina multidentata.
