Neocaridina Red Onyx Shrimp (Neocaridina davidi “Red Onyx”).

Neocaridina Red Onyx Shrimp (scientifically known as Neocaridina davidi) are a selectively bred variant of the popular Red Cherry Shrimp. They stand out with their captivating coloration, showcasing a unique mix of deep red and white, reminiscent of the alluring beauty of red onyx gemstones. Their small size, peaceful nature, and remarkable ability to thrive in a range of water conditions make them a fantastic addition to both beginner and experienced aquarium setups.

Habitat: Originating from Taiwan, Neocaridina Red Onyx Shrimp inhabit freshwater environments, often found in slow-moving streams and densely vegetated areas. Recreating their natural habitat in your aquarium is essential for their well-being. Consider these key points when setting up their home:

1. Tank Size: A minimum of 5 gallons (19 liters) is suitable for a small colony of Neocaridina Red Onyx Shrimp. A larger tank can provide more stability in water parameters and a more forgiving environment.
2. Substrate: Use a fine-grain substrate, such as sand or small gravel, which will allow the shrimp to forage and graze for food.
3. Plants: Live aquatic plants like Java Moss, Anubias, and Marimo Moss Balls provide hiding spots and grazing surfaces for the shrimp. Plants also help maintain water quality.
4. Decor: Incorporate driftwood, small caves, and smooth rocks to offer hiding places and create a natural-looking environment.
5. Filtration: A gentle sponge filter or a low-flow hang-on-back filter is recommended. Shrimp are sensitive to strong currents, which can stress them.
6. Water Parameters:
   • Temperature: 68°F – 78°F (20°C – 25.5°C)
   • pH: 6.5 – 7.5
   • GH (General Hardness): 6 – 10 dGH
   • KH (Carbonate Hardness): 2 – 8 dKH
   • Ammonia, Nitrite, Nitrate: Keep these levels at zero; regular water changes and proper cycling are crucial.

Care and Feeding: Neocaridina Red Onyx Shrimp are relatively low-maintenance, but attentive care ensures their optimal health:

• Provide a balanced diet with high-quality shrimp pellets, blanched vegetables (like spinach or zucchini), and occasional treats like spirulina powder.
• Avoid overfeeding, as uneaten food can degrade water quality.
• Maintain stable water parameters by performing regular water changes (10-20% weekly) to prevent ammonia and nitrite buildup.
• Introduce new shrimp slowly to prevent stress and potential disease transmission.

Breeding: These shrimp are prolific breeders under proper conditions. Female shrimp carry eggs under their abdomens until they hatch into miniature versions of the adults. Providing plenty of hiding spots for newborn shrimp helps increase their survival rate.
