Snowflake Shrimp Care Guide: White-Spotted Neocaridina

Snowflake shrimp are a selectively bred colour morph of Neocaridina davidi, distinguished by their translucent bodies speckled with white, snowflake-like markings. This snowflake shrimp care guide from Gensou Aquascaping at 5 Everton Park, Singapore, covers everything from tank setup to colony management. Hardy, prolific, and endlessly entertaining to watch, snowflake shrimp make an ideal entry point into the world of ornamental shrimp keeping.

Appearance and Identification

True snowflake shrimp display white or cream-coloured spots and patches across a clear to slightly milky body. The effect resembles scattered snowflakes under the right lighting. Females are larger at 2.5-3 cm and show a more pronounced saddle (egg development area) behind the head. Males stay slimmer at around 2 cm. The white spotting varies in intensity between individuals, and selective breeding over generations can increase the density and contrast of the pattern.

Tank Setup

A 20-litre nano tank is sufficient for a starter colony of ten to fifteen shrimp. Planted tanks with Java moss, Taxiphyllum barbieri, Bucephalandra, and Anubias provide excellent grazing surfaces where biofilm accumulates. An inert substrate like ADA La Plata Sand or fine gravel works well; active substrates designed for Caridina shrimp are unnecessary for this hardy Neocaridina variety. A small sponge filter keeps the water clean without risking baby shrimp being sucked into an intake.

Water Parameters

Neocaridina davidi tolerates a broad range: pH 6.5-8.0, GH 4-14, KH 2-8, and temperatures of 20-28 °C. Singapore’s tap water at GH 2-4 sits at the softer end, which is acceptable but benefits from a small amount of mineral supplementation using a GH+ product like SaltyShrimp GH/KH+. Dose to achieve GH 6-8 for best moulting success. Remineralise your water change water before adding it to the tank, never directly into the shrimp tank. Temperature is rarely an issue in Singapore, though keeping the tank below 28 °C encourages higher breeding rates.

Feeding

Snowflake shrimp are omnivorous scavengers that graze constantly on biofilm, algae, and decaying plant matter. In a well-established planted tank, supplementary feeding is needed only two to three times per week. Offer a small pinch of quality shrimp pellets, blanched spinach, or mulberry leaves. Snowflake food (a commercially available soya-based product) is not related to the shrimp variety by name but is a popular supplementary food in Singapore’s shrimp-keeping community. Remove uneaten food after two hours to prevent ammonia spikes in small tanks.

Breeding

Breeding is effortless under stable conditions. Females carry 20-40 eggs in a greenish-yellow clutch under their swimmerets for approximately 28-30 days. Shrimplets are born as tiny replicas of the adults, around 2 mm long, and require no special food. They graze on biofilm and crushed powdered food from day one. A healthy colony doubles in size every two to three months. To maintain strong white colouration, cull individuals that show excessive brown or yellow tinting and keep only the cleanest-looking specimens for breeding.

Common Issues

Failed moults are the number-one killer in Neocaridina colonies and almost always trace back to insufficient GH or sudden parameter swings. The white ring of death, a white band separating the head from the body, indicates a moult that failed midway. Ensure GH stays above 5 and avoid large water changes that alter parameters abruptly. Copper is lethal to shrimp even in trace amounts: check any medications, fertilisers, or tap water treatments for copper content before use.

Colony Management Tips

Once your colony reaches 50-100 shrimp in a nano tank, it is time to thin out or upgrade. Overcrowded shrimp tanks see declining water quality and smaller clutch sizes. Excess shrimp sell easily on Carousell for $1-2 each, or you can set up additional tanks to expand your colony. Snowflake shrimp interbreed freely with other Neocaridina colour morphs, so keep them in a species-only tank if you want to preserve the distinctive white patterning across generations.
