Shrimp Blue Nancy

The Blue Nancy Shrimp is a striking ornamental freshwater Neocaridina variety admired for its rich blue coloration and consistent body tone. This selectively bred shrimp brings strong visual contrast to planted aquariums, especially when displayed against green aquascapes or dark substrates. Hardy, active, and easy to maintain, the Blue Nancy Shrimp is a popular choice for both beginner and experienced aquarists seeking a reliable colony shrimp with strong colour presence.

Features of Shrimp Blue Nancy

• Deep, consistent blue body coloration

• Selectively bred Neocaridina davidi variety

• Small adult size of approximately 2.5–3 cm

• Peaceful and highly social in groups

• Constant algae and biofilm grazer

• Ideal for planted nano and community aquariums

• Hardy and adaptable freshwater shrimp

The best aquarium size for Shrimp Blue Nancy

The Blue Nancy Shrimp thrives in stable freshwater aquariums with a minimum volume of 20–30 litres. Larger aquariums are recommended for breeding colonies, as they provide improved water stability and more surface area for natural grazing.

Maintain water temperatures between 20–26 °C, a pH range of 6.5–7.8, and moderate hardness. Stable conditions are more important than exact parameters, making this shrimp highly suitable for established community or planted tanks.

Tank Mate Compatibility for Shrimp Blue Nancy

The Blue Nancy Shrimp is best kept with peaceful, shrimp-safe species that will not prey on juveniles or adults, including:

• Chili Rasbora

• Ember Tetra

• Otocinclus Catfish

• Endler’s Livebearer

• Pygmy Corydoras

Avoid aggressive fish, large cichlids, and any species known to hunt shrimp, as these will significantly reduce colony survival.

Diet for Shrimp Blue Nancy

The Blue Nancy Shrimp is a continuous grazer that feeds on algae, biofilm, and organic detritus within the aquarium. Supplement their diet with high-quality shrimp pellets, algae wafers, and blanched vegetables such as zucchini, spinach, and cucumber.

A balanced diet supports strong moulting cycles, healthy growth, and stable blue pigmentation. Feed sparingly to avoid excess waste and maintain optimal water quality.

Aquarium Setup Shrimp Blue Nancy

Aquarium Filtration

Gentle sponge filtration or low-flow filtration systems are ideal, providing safe water movement and strong biological stability without risking shrimp damage.

Aquarium Plants

Dense planting with mosses, Anubias, and Bucephalandra provides essential grazing surfaces, cover, and breeding zones for shrimplets.

Aquarium Lighting

Low to moderate lighting enhances blue colour intensity while encouraging natural biofilm growth throughout the aquarium.

Aquarium Heating

A stable heater should maintain temperatures between 20–26 °C, avoiding rapid fluctuations that can stress moulting shrimp.

Aquarium Substrate

Dark or neutral substrates are preferred, as they enhance the visibility of the blue coloration and create strong visual contrast in aquascapes.

Aquarium Decorations

Include driftwood, leaf litter, and fine rock structures such as lava rock to maximise grazing surfaces and create natural shelter zones for colony development.
