Red Cherry Shrimp Breeding Guide
How to breed Red Cherry Shrimp (Neocaridina davidi): sexing, conditioning, berried females carrying 20-30 eggs for about three weeks, and raising shrimplets that hatch fully formed.
Overview
The Red Cherry Shrimp is a selectively bred red color morph of Neocaridina davidi, a freshwater shrimp of the family Atyidae. It is the most widely kept dwarf shrimp in the hobby and breeds readily in a stable, mature tank. Reproduction needs only a sexed pair of mature shrimp, steady water parameters, and a reliable food source. There is no larval stage: females carry the eggs externally and release miniature shrimplets that are direct copies of the adults.
Sexing
Females are larger, show a more opaque and richer red, and have a deeper, downward-curved tail (pleon) used to hold eggs. Males stay smaller and are typically paler. A mature female develops a yellow or green triangular "saddle" on her back, which is the egg mass forming in the ovaries before they pass to the swimmerets.
Conditioning
Maintain stable parameters in the reported range for the species: temperature about 22-26 °C and pH roughly 6.5-7.8, with steady hardness. Feed a varied diet; as a detritivore the shrimp graze biofilm, algae and detritus, and also consume their own molts. A well-established tank with live plants such as moss provides grazing surfaces and cover that support steady breeding.
Breeding Setup
A small species-only tank with gentle, shrimp-safe filtration and dense plant cover works best. Avoid fish that prey on shrimplets. Color in this morph is a heritable selectively bred trait, and the red trait behaves as a recessive gene. Because cross-breeding different Neocaridina davidi color morphs produces brown, wild-type offspring, keep Red Cherry separate from other morphs to hold a stable red line.
Spawning & Berried Females
Mating follows a female's molt: she releases pheromones, the male transfers sperm, and the eggs are fertilized externally as they move to the pleopods. A berried female carries roughly 20-30 eggs, fanning and cleaning them for about two to three weeks until they hatch. First-time or stressed females may drop a clutch, so parameters should be kept steady during incubation.
Shrimplet Care
Newly hatched shrimplets are about 1 mm and are fully formed copies of the adults, grazing immediately on biofilm. They reach sexual maturity at roughly two to three months and live about one to two years. To keep grade high, breeders cull lower-color individuals so the brightest reds dominate the breeding stock.
Common Challenges
Color dilution is the main risk: mixing morphs or weak culling lets offspring drift toward translucent or brown wild-type tones. Unstable water and copper exposure harm shrimp and developing eggs. Lower-grade reds are normal in any clutch and are simply removed from the breeding line rather than treated as defects.
