Red Cherry shrimp

Neocaridina davidi "Red"

The shrimp that popularized the hobby: bright cherry-red body — the most iconic and best-selling Neocaridina in the world. Extremely easy to keep: tolerant, adaptable, very prolific. Grading from Sakura to Painted Fire Red based on coverage and opacity of red. Tireless algae and biofilm grazer — an essential ally for every planted aquarium. Do not mix different color varieties (color reverts to wild-type over generations). Ideal for absolute beginners.

Species description

Geographical Origin and Habitat: The Cherry Red Shrimp is arguably the most famous, highly stabilized, and profoundly beloved captive-bred dwarf shrimp in the world. It originates from wild Neocaridina davidi (formerly N. heteropoda) lines natively found in the diverse, densely vegetated, slow-moving freshwater streams, ponds, and agricultural canals of eastern China and Taiwan. The captive aquarium "biotope" requires a heavily planted, highly mature environment characterized by dense thickets of fine-leaved aquatic plants, branching driftwood, and abundant natural biofilm.

Taxonomy: Scientifically classified within the Atyidae family, it is a spectacular, biologically indestructible, and incredibly adaptable dwarf shrimp. Morphologically, fully mature adults reach a maximum of roughly 2.5 to 3.0 centimeters (1.0-1.2 inches) in length. It possesses a deeply compact, laterally compressed, heavily armored exoskeleton typical of the Neocaridina genus. The "Red" or "Cherry" is the original, iconic selective mutation that launched the dwarf shrimp hobby, meticulously bred over decades to express a stunning, deeply saturated red coloration.

Social Behavior: They are highly intelligent, entirely non-aggressive, and deeply communal benthic (bottom-dwelling) invertebrates. They are completely harmless and absolutely MUST be kept in a sizable colony (absolute minimum 10-15 individuals) to establish critical security, disperse shyness, and encourage breeding. In the aquarium, they possess a fascinating, intensely busy, and constant scavenging lifestyle. They spend 100% of their entire day continuously crawling over every square inch of the substrate, specifically focusing on complex moss structures, meticulously picking off microscopic biofilm.

Coloration and Sexual Dimorphism: Sexual dimorphism is absolute and unmistakable when fully mature; mature females are significantly larger, possess a vastly deeper, more rounded abdomen, display a distinct yellowish "saddle" (developing eggs) behind the head, and crucially, are vastly more colorful than males. The coloration of the Cherry Red Shrimp (especially high grades like "Painted Fire Red") is breathtaking: the body is entirely covered in a completely solid, fiercely glowing, opaque crimson or blood-red pigment. Males remain mostly clear with slight red speckling.

Care, breeding and tankmates

Tank Setup: The aquarium architecture MUST flawlessly accommodate their highly active, scavenging nature and provide massive security. A minimum 30-liter (8-gallon) tank is perfectly suitable for a dedicated colony. The absolute most critical requirement is overwhelming structural cover and surface area for biofilm generation; the tank MUST feature dense thickets of fine-leaved plants, large pieces of branching driftwood, and specifically, dense carpets of aquatic moss (Java Moss or Christmas Moss). A dark, inert substrate heavily contrasts their red color beautifully.

Diet and Feeding: They are highly active, continuous scavengers and detritivores that feed exclusively by meticulously picking microscopic biofilm, soft green algae, and decaying organic matter off surfaces. In the aquarium, their diet is notoriously easy but MUST be comprehensive. While they will constantly graze on natural tank biofilm, they strictly MUST be fed a heavily vegetable-based micro-diet. Daily offerings of high-quality sinking shrimp pellets, powdered spirulina, bacter-AE, and specifically, blanched organic vegetables (spinach, carrots to boost red color) are mandatory.

Water Quality: Neocaridina are universally famous for being incredibly robust, adaptable, and completely forgiving of minor parameter fluctuations, making them the ultimate beginner shrimp. They thrive in a wide range of temperatures (18-28°C / 64-82°F) and do not require a heater in most homes. Crucially, they absolutely require moderately hard to hard water (GH 6-12) and a neutral to slightly alkaline pH (7.0 - 8.0) to maintain their thick exoskeletons. They possess zero tolerance for Ammonia or Nitrites; a highly mature, cycled filter is absolutely mandatory.

Compatibility and Tankmates: Compatibility is strictly limited by their microscopic size and completely defenseless nature. They are the perfect, spectacular centerpiece for a dedicated, peaceful nano shrimp biotope. If housed in a community, tankmates MUST be exceptionally peaceful, tiny micro-fish. Excellent companions include Boraras species (Chili Rasboras), Pygmy Corydoras, and peaceful Otocinclus. They MUST NEVER be housed with fast, aggressive mid-water fish (like Zebra Danios) or any standard predatory fish (like Cichlids, Bettas, or Gouramis) that will violently hunt and eat them.

Aquarium Breeding: Breeding is spectacularly prolific, incredibly fast, and straightforward in a dedicated aquarium, requiring absolutely zero special intervention (they are often called the "guppies" of the shrimp world). They are direct developers. Triggered by clean water and abundant food, mature females will carry 20-30 yellow/green eggs under their abdomen for roughly 3-4 weeks. When they hatch, the babies emerge as microscopic, fully formed replicas of the adults. The babies are profoundly delicate; massive tangles of moss are absolutely mandatory to ensure survival.

Risks and Diseases: The absolute greatest physical risk is rapid, lethal toxicity; like all dwarf shrimp, they possess absolute zero tolerance for Copper, heavy metals, or chemical medications (especially fish Ich treatments), which will kill the entire colony instantly. The second major risk is lethal predation; placing them with standard community fish guarantees they will be hunted to extinction. Finally, severe physiological collapse (molting failure) occurs if the GH parameters are too soft; hard water is unconditionally mandatory for their shells.
