Red Rilli Shrimp

Neocaridina Shrimp – Care Guide & Aquarium Companions

Neocaridina shrimp are colourful, peaceful and easy-to-care-for freshwater shrimp, making them one of the most popular choices for planted and community aquariums. They are available in many attractive colours including Red Cherry, Blue Dream, Yellow, Orange, Chocolate and more.

They are excellent scavengers and spend most of their time grazing on algae, biofilm and leftover food around plants, rocks and driftwood.

Aquarium Care

Tank Size:
A minimum of around 20 litres is recommended, although larger and well-established aquariums provide more stable water conditions.

Water Temperature:
Generally 20°C – 26°C.

pH Range:
Approximately 6.5 – 8.0.

Water Hardness:
Moderately hard water is generally preferred. Stable water parameters are more important than constantly adjusting the water.

Aquarium Setup:
A mature planted aquarium with moss, driftwood, rocks and plenty of hiding spaces is ideal. Plants and moss provide grazing surfaces and protection for baby shrimp.

Gentle filtration, such as a sponge filter, is recommended to prevent small shrimp from being pulled into the filter.

Feeding

Neocaridina shrimp naturally feed on algae and biofilm but should also be provided with a balanced diet including:

• Shrimp pellets or wafers

• Algae-based foods

• Blanched vegetables

• Biofilm and natural algae

• Occasional protein-rich shrimp food

• Indian almond leaves and other suitable botanicals

Avoid overfeeding, as excess food can quickly affect water quality.

Behaviour & Grouping

Neocaridina shrimp are peaceful and social. They can be kept in colonies and often breed readily when aquarium conditions are suitable.

Keeping a group of at least 8–10 shrimp is recommended when starting a colony.

Females may carry eggs beneath their body, and once hatched, the young shrimp are miniature versions of the adults.

Suitable Tank Companions

The safest option for breeding is a shrimp-only aquarium.

They can also be kept with small and peaceful species such as:

Small Rasboras • Small Tetras • Otocinclus • Corydoras • Snails and other peaceful nano fish

However, almost all fish may eat newborn shrimp if given the opportunity. Dense plants and moss provide better survival chances for baby shrimp.

Avoid keeping Neocaridina with large, aggressive or predatory fish.

Important Note

Neocaridina shrimp are sensitive to sudden changes in water parameters. Always acclimate new shrimp slowly before introducing them into the aquarium.

Avoid medications or aquarium products containing copper, as high levels can be harmful to shrimp.

With stable water conditions, good-quality food and plenty of natural grazing areas, Neocaridina shrimp can develop vibrant colours and establish thriving colonies in the aquarium.
