For Neocaridina Blue Carbon Shrimp, water parameters aren’t just numbers—they’re the difference between a colony that merely survives and one that flourishes. These striking blue invertebrates have evolved to thrive within specific water conditions, and maintaining these parameters is crucial for their health, coloration, and breeding success.
Survival vs. Thriving Parameters
While Blue Carbon Shrimp can survive in a relatively broad range of water conditions, there’s a narrower sweet spot where they truly thrive. Consider these differences:
Survival Range:
- pH: 6.0-8.0
- Temperature: 65-85°F (18-29°C)
- TDS: 100-400 ppm
- GH: 4-14 dGH
- KH: 2-10 dKH
Optimal Range for Thriving:
- pH: 6.8-7.5
- Temperature: 70-76°F (21-24°C)
- TDS: 150-250 ppm
- GH: 6-8 dGH
- KH: 3-5 dKH
When kept within these optimal parameters, Blue Carbon Shrimp exhibits:
- More vibrant blue coloration
- Active breeding behavior
- Regular molting
- Increased activity levels
- Better survival rates for shrimplets
The Paramount Importance of Stability
Perhaps even more critical than the exact parameters is their stability. Sudden changes in water chemistry can trigger stress responses in shrimp, leading to:
- Delayed or problematic molting
- Reduced breeding
- Color fading
- Increased susceptibility to disease
- Higher mortality rates
This sensitivity to parameter fluctuations stems from their evolution in stable, mineral-rich waters. Even if your parameters aren’t perfect, maintaining consistency will typically yield better results than chasing “perfect” numbers while creating instability.
