Neocaridina davidi, commonly known as the Cherry Shrimp, is a small, freshwater invertebrate belonging to the Atyidae family. It is highly prized in the aquarium hobby for its vibrant coloration, ease of care, and prolific breeding. Originating from Taiwan, this species has been selectively bred to enhance its red pigmentation, leading to various color grades. They are detritivores and grazers, playing an important role in maintaining tank cleanliness by consuming algae and biofilm.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- Wild type Neocaridina davidi are typically brownish or greenish, often translucent. Through selective breeding, a wide range of colors has been developed, with red (Cherry Shrimp) being the most common. Other colors include yellow, orange, blue, green, black, and white. The intensity of coloration can vary based on diet, stress, genetics, and water parameters. Females are generally more intensely colored than males.

Consigli per l'identificazione
Size and Shape
Adults typically reach 2-3 cm (0.8-1.2 inches). They have a typical shrimp-like elongated body with a curved abdomen.
Coloration
While wild types are drab, captive-bred Neocaridina davidi are known for their vibrant and diverse color morphs, especially red. The intensity of color is a key identifier for specific grades.
Rostrum
The rostrum is relatively short and lacks teeth on the underside, distinguishing it from some Caridina species.
Sexing
Females are generally larger, more intensely colored, and have a noticeable 'saddle' (undeveloped eggs) behind their head and a broader, more rounded underside (pleura) for carrying eggs. Males are smaller and less colorful.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Typically found in shallow waters of streams, ponds, and slow-moving rivers.
- Ambiente
- Prefers environments with abundant aquatic vegetation, leaf litter, and submerged structures that provide shelter and a source of biofilm and detritus. They are often found grazing on surfaces.
- Areale geografico
- Native to Taiwan and parts of mainland China. Introduced globally through the aquarium trade.

Fatti chiave
Color Gradesinteresting
Cherry Shrimp are graded based on the intensity and coverage of their red coloration, ranging from 'Cherry' (light red, some clear spots) to 'Fire Red' (solid red) and 'Painted Fire Red' or 'Bloody Mary' (deep, opaque red with no clear spots).
Prolific Breedersbehavior
Neocaridina davidi are known for their rapid breeding. Females can carry 20-50 eggs every 4-6 weeks, and the young hatch as miniature versions of the adults, making them easy to propagate in captivity.
Algae Eatersbehavior
These shrimp are excellent algae eaters, consuming various types of algae, biofilm, and detritus, which helps maintain a clean and healthy aquarium environment.
Sexual Dimorphismbehavior
Females are typically larger and more vibrantly colored than males, especially when gravid (carrying eggs). They also develop a 'saddle' of undeveloped eggs behind their head.
Copper Sensitivityinteresting
Like most invertebrates, Neocaridina davidi are highly sensitive to copper, which is often found in medications for fish. Even trace amounts can be lethal.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: not recommended
- Note sul maneggio: These shrimp are delicate and should be handled with care. Avoid exposing them to air for extended periods. When transferring, use a net with fine mesh or a cup to minimize stress and injury. Ensure hands are free of soap, lotions, or other chemicals.
Specie simili
Amano Shrimp
Caridina multidentata
Amano shrimp are larger (up to 5 cm), typically translucent with small dark spots or dashes along their sides, and require brackish water for larval development, making them harder to breed in captivity. Neocaridina davidi are smaller, come in solid colors, and breed readily in freshwater.
Tiger Shrimp
Caridina mariae
Tiger shrimp have distinct black or blue stripes on a lighter body, and generally prefer slightly cooler and softer water with a lower pH than Neocaridina davidi. Their rostrum also has more prominent teeth.
Crystal Red Shrimp
Caridina cantonensis
Crystal Red Shrimp (CRS) are characterized by their striking red and white banded patterns. They are more sensitive to water parameters, requiring softer, more acidic water, and are generally more challenging to keep and breed than Neocaridina davidi.
