Snowball Shrimp Care Guide: Pure White Neocaridina

Table of Contents

Introduction

Among the many colour variants of Neocaridina davidi, the snowball shrimp stands out for its striking, pure white colouration. Named for the visible white eggs carried by berried females — which resemble tiny snowballs — this variety has gained a devoted following among shrimp keepers worldwide. This snowball shrimp care guide covers everything Singapore hobbyists need to know about keeping, feeding, breeding, and enjoying these beautiful white Neocaridina in tropical aquariums. This guide sits inside our broader Tropical Fish Species Master Index reference.

Snowball shrimp offer the same beginner-friendly hardiness that makes Neocaridina the most popular dwarf shrimp in the hobby, combined with a clean, elegant aesthetic that complements virtually any aquascape. Whether you are a first-time shrimp keeper setting up a nano tank in your HDB flat or an experienced breeder expanding your colony, snowball shrimp are a rewarding choice.

Species Overview and Origin

Snowball shrimp are a selectively bred colour morph of Neocaridina davidi (formerly Neocaridina heteropoda), the same species that gives us cherry shrimp, blue dream shrimp, yellow shrimp, and many other popular varieties. The wild form originates from freshwater streams and ponds in Taiwan and parts of mainland China.

The snowball variety was developed through selective breeding for white or translucent body colouration. High-quality specimens display an opaque, milky white body with minimal transparency. Females are typically more intensely coloured than males, and their white saddle (visible egg development behind the head) and white eggs make them particularly striking.

Quick Species Profile

Tank Setup and Water Parameters

Snowball shrimp thrive in well-established, mature aquariums with stable water parameters. Like all Neocaridina, they are adaptable, but they do best when conditions are consistent rather than fluctuating.

Tank Size

A 20-litre (5-gallon) nano tank is sufficient for a starter colony of 10–15 snowball shrimp. However, a 40-litre tank provides more stable water parameters and room for the colony to grow. Many Singapore shrimp keepers run dedicated Neocaridina breeding tanks in the 30–60 litre range, which allows a colony to establish itself comfortably.

Recommended Water Parameters

Substrate and Decoration

Snowball shrimp display beautifully against dark substrates. A fine-grained dark soil or sand makes their white bodies pop visually. For a breeding-focused setup, inert substrates (sand, gravel) are preferable to active soil substrates, as active soils can lower pH and GH beyond the ideal range for Neocaridina.

Include plenty of surfaces for biofilm growth:

• Driftwood: Provides surfaces for grazing and hiding spots
• Mosses: Java moss, Christmas moss, and flame moss are ideal — they harbour microorganisms that shrimp feed on and provide shelter for shrimplets
• Cholla wood: Develops thick biofilm quickly and provides hiding places
• Indian almond leaves: Release tannins with mild antibacterial properties and develop biofilm that shrimp graze on constantly
• Ceramic tubes and shrimp shelters: Available at most local fish shops

Filtration

A sponge filter is the gold standard for shrimp tanks. It provides biological filtration, gentle water movement, and a large surface for biofilm growth — all without the risk of sucking up baby shrimp. If using a hang-on-back or canister filter, always cover the intake with a fine sponge pre-filter.

Feeding and Diet

Snowball shrimp are opportunistic omnivores that spend most of their waking hours grazing on biofilm, algae, and organic detritus. In a well-established tank with mature biofilm, supplemental feeding should be moderate to avoid overfeeding and water quality issues.

Recommended Foods

• Staple: High-quality shrimp-specific pellets or granules (brands like Shrimp King, Glasgarten, Borneowild are popular in Singapore)
• Biofilm boosters: Bacter AE or similar products that promote biofilm growth
• Blanched vegetables: Spinach, zucchini, cucumber, kale — remove uneaten portions after 6–8 hours
• Protein supplements: Freeze-dried or frozen bloodworms, daphnia (once or twice weekly)
• Mineral supplements: Mineral stones, cuttlebone pieces for calcium
• Dried leaves: Indian almond leaves, mulberry leaves, guava leaves — these decompose slowly and provide continuous grazing material

Feeding Schedule

Feed supplemental food every other day or three times per week. A good rule is to offer a small amount and observe — if it is not consumed within two to three hours, you are feeding too much. In a mature tank with established biofilm, shrimp may need very little supplemental food, especially if the colony is small relative to the tank size.

Behaviour and Temperament

Snowball shrimp are peaceful, social creatures that display fascinating behaviour when kept in a comfortable, secure environment. A well-settled colony is active around the clock, with shrimp constantly grazing, exploring, and interacting.

Notable Behaviours

• Grazing: The primary activity — shrimp use their small front legs to pick at surfaces, consuming biofilm and algae particle by particle
• Swimming frenzy: When a female moults and releases pheromones, males swim rapidly around the tank searching for her. This “mating dance” is dramatic but harmless
• Moulting: Shrimp shed their exoskeleton regularly as they grow. After moulting, they may hide for 24–48 hours while their new shell hardens
• Food swarming: When supplemental food is dropped in, shrimp congregate rapidly — a sign of a healthy, active colony

Snowball shrimp are non-aggressive and never harm tank mates. Their only defence is retreat, so providing ample hiding spots is essential for their sense of security.

Suitable Tank Mates

The safest tank mates for snowball shrimp are other small, peaceful invertebrates and fish that will not predate on adults or shrimplets.

Safe Tank Mates

Tank Mates to Avoid

• Most fish larger than 4 cm — they may eat shrimplets or stress adults
• Bettas — some individuals actively hunt shrimp
• Guppies and endlers — will eat baby shrimp
• Any cichlid species
• Crayfish — will catch and eat shrimp

For maximum breeding success, a species-only tank or a shrimp-and-snails-only setup is recommended.

Breeding Snowball Shrimp

One of the great joys of keeping Neocaridina shrimp is how readily they breed. Snowball shrimp are no exception — with stable parameters, good nutrition, and a stress-free environment, a colony will grow steadily.

Sexing Snowball Shrimp

• Females: Larger (2.5–3 cm), more intensely white, with a visible saddle (egg development area) behind the head. When carrying eggs, the white egg clutch is visible under the tail.
• Males: Smaller (2–2.5 cm), slimmer, slightly more translucent. Longer antennae relative to body size.

Breeding Process

1. Moulting trigger: A mature female moults and releases pheromones into the water.
2. Mating frenzy: Males swim rapidly through the tank, searching for the newly moulted female.
3. Fertilisation: A male locates and mates with the female. The process takes only seconds.
4. Egg carrying: The female transfers fertilised eggs to her pleopods (swimmerets) under her tail, where she fans them constantly to keep them oxygenated. The white eggs are clearly visible — the “snowball” effect that gives the variety its name.
5. Hatching: Eggs hatch in 28–35 days at tropical temperatures. Baby shrimp emerge as miniature versions of the adults, fully independent from birth.

Maximising Shrimplet Survival

• Provide dense moss and fine-leaved plants where shrimplets can hide and graze
• Avoid fish that eat fry — a shrimp-only tank yields the highest survival rate
• Ensure sponge filter covers on all filter intakes
• Maintain stable water parameters — sudden changes kill shrimplets more readily than adults
• Use biofilm-boosting products to ensure tiny shrimplets have access to microscopic food

Colour Grading and Selection

Not all snowball shrimp are equally white. Like other Neocaridina varieties, colour intensity varies and can be improved through selective breeding.

Grading Guide

To maintain and improve colour quality over generations, periodically remove lower-grade shrimp from your breeding colony. This prevents colour dilution and gradually concentrates the genes for intense white pigmentation. Many Singapore shrimp breeders maintain a “display colony” of their best specimens and a separate “grow-out” tank for culls.

Common Issues and Health

• White ring of death: A white band around the body where the exoskeleton has cracked during moulting. Usually caused by mineral deficiency (low GH) or rapid parameter changes. Supplement with GH+ remineraliser and ensure stable water conditions.
• Failed moults: Shrimp unable to shed their old exoskeleton. Related to calcium and mineral deficiency. Ensure GH is at least 6 dGH and provide cuttlebone or mineral supplements.
• Bacterial infections: Opaque patches on the body (distinct from normal white colouration), lethargy, or pink discolouration. Quarantine affected individuals and improve water quality.
• Parasites: Ellobiopsidae (green fungus), scutariella (white worms on the head), or vorticella (white fuzzy growths). Salt dips can treat some external parasites; severely affected individuals should be isolated.
• Heat stress: In Singapore’s climate, tank temperatures can occasionally exceed 30 °C during heatwaves. Use a small clip-on fan directed at the water surface to reduce temperature through evaporative cooling.

Frequently Asked Questions

Can I keep snowball shrimp with cherry shrimp?

You can, but they will interbreed since both are Neocaridina davidi variants. Offspring will likely revert to wild-type brownish colouration over several generations. If you want to maintain the pure white colour, keep snowball shrimp in a species-only tank or only with non-Neocaridina invertebrates.

Do snowball shrimp need a heater in Singapore?

No. Singapore’s ambient temperature keeps tank water in the 26–30 °C range, which is within the snowball shrimp’s tolerance. In fact, overheating is more of a concern — during particularly hot periods, consider using a clip-on fan or placing the tank away from direct sunlight.

How many snowball shrimp should I start with?

Begin with at least 10–15 shrimp to ensure a good mix of males and females and to establish a viable breeding colony. Starting with fewer increases the risk of inbreeding and slow colony growth. Many Singapore shrimp keepers start with 20 for a healthier genetic foundation.

Why are my snowball shrimp turning clear or transparent?

Reduced opacity can indicate stress, poor water quality, inadequate diet, or simply lower genetic quality. Check your water parameters (especially GH and TDS), ensure varied nutrition, and selectively breed only the whitest individuals. Some shrimp also appear more translucent just after moulting, which is temporary.
