How to Breed Neocaridina Shrimp: Cherry Shrimp and Beyond
Cherry shrimp are one of the easiest aquarium inhabitants to breed — give them clean water, decent food, and a little patience, and they will do the rest. This breed neocaridina shrimp guide from Gensou Aquascaping at 5 Everton Park, Singapore, takes you from your first berried female to a thriving colony of vibrant, selectively graded Neocaridina davidi. Singapore’s soft, warm tap water is actually well-suited to these hardy shrimp with only minor adjustments.
Setting Up the Breeding Tank
A dedicated 20-40 litre tank produces the best results. Larger tanks work too but make it harder to catch and grade shrimp later. Use a sponge filter — it provides biological filtration without sucking up shrimplets. An active buffering substrate is unnecessary for Neocaridina; plain inert gravel or sand works perfectly. Add plenty of moss — Java moss, Christmas moss, or flame moss — which harbours biofilm that shrimplets graze on from day one.
Cycle the tank fully before adding shrimp. Ammonia and nitrite must read zero. Neocaridina tolerate a range of parameters, but for breeding you want stability above all else.
Ideal Water Parameters
Neocaridina thrive in a wide range, but breeding is most productive at a temperature of 24-26°C, pH 6.8-7.5, GH 6-8, and KH 2-5. Singapore’s PUB tap water typically comes out soft (GH 2-4), so remineralising with a GH booster like Salty Shrimp GH+ brings it into the ideal range. Add the remineraliser to your water change bucket, not directly to the tank.
Temperature matters more than most guides suggest. At 28-30°C — common in un-airconditioned Singapore rooms — shrimp metabolise faster, breed more frequently, but also live shorter lives. A small fan across the water surface can drop temperature by 2-3°C, extending lifespan and producing healthier offspring.
Starting Your Colony
Begin with at least 10-15 shrimp from the same colour line. Mixing colours — red cherry with blue dream, for example — produces wild-type brown offspring within a few generations. If you want to maintain or improve colour, keep each variety in its own tank. Purchase from local breeders on Carousell or dedicated shrimp sellers rather than mass imports; locally bred stock is already adapted to Singapore water.
A healthy colony reaches breeding age at roughly 3-4 months. Females are larger, more intensely coloured, and develop a curved underside (the “saddle”) behind the head where eggs form before fertilisation.
The Breeding Process
Mating happens after a female moults. She releases pheromones into the water, triggering a “mating frenzy” where males swim erratically searching for her. Fertilisation is brief. Within hours, the female transfers eggs to her swimmerets under her tail, where she fans and carries them for 25-35 days until they hatch as miniature versions of the adults.
A berried female carrying 20-40 eggs is a common sight in a well-established colony. Do not disturb her. Avoid major water parameter swings during the carrying period — sudden changes can cause her to drop the eggs prematurely.
Feeding for Colour and Growth
Biofilm growing on moss, wood, and surfaces is the primary food source for shrimplets and contributes to adult nutrition. Supplement with a quality shrimp pellet 3-4 times per week — only as much as the colony consumes in two hours. Blanched spinach, mulberry leaves, and Indian almond leaves make excellent occasional treats that also promote biofilm growth.
Mineral-rich foods like snowflake pellets (soybean husks) break down slowly and feed both shrimp and beneficial bacteria. Overfeeding is the biggest killer of shrimp colonies — uneaten food decays, spikes ammonia, and wipes out shrimplets before you notice.
Grading and Selective Breeding
Not every shrimp in a colony will be deeply coloured. Grading means separating the most vibrant individuals for breeding and moving less colourful ones to a separate tank or selling them. For cherry shrimp, grades range from the lowest (Cherry, with translucent patches) to the highest (Painted Fire Red, solid opaque colour on legs and body).
Grade every 4-6 weeks as juveniles mature. Use a clear container to isolate individuals for inspection. Over several generations, consistent selective breeding noticeably intensifies colour. Patience is essential — dramatic improvement takes 6-12 months of disciplined grading.
Common Problems and Solutions
Failed moults are the most frequent cause of shrimp death. They result from insufficient minerals in the water — ensure GH stays above 5 with regular remineralisation. Planaria and hydra prey on shrimplets; treat with fenbendazole (Panacur) at 0.1 grams per 40 litres if you spot these pests. Avoid copper-based medications in any shrimp tank — copper is lethal even in trace amounts.
Scaling Up Your Colony
A well-managed 30-litre tank can sustain 200+ shrimp, but growth eventually plateaus as the colony self-regulates. If you want to scale production, set up multiple breeding tanks rather than cramming more into one. Selling surplus shrimp on Carousell at $1-3 SGD each for common grades or $5-10 SGD for high grades can offset your hobby costs nicely. Gensou Aquascaping has seen many hobbyists in Singapore turn a casual interest in cherry shrimp into a genuinely productive side pursuit.
