Caridina species thrive in tanks with active soil that lowers the pH to an optimal range of 5 to 6.5, which is perfect for freshwater shrimp, especially Caridina varieties.
The recommended parameters are:
pH: 5.5 to 6.5
GH: 4-6
KH: 0 – 1
Nitrate: 0-20 ppm for optimal results.
Temperature: Maintain a stable range of 20-23 degrees Celsius.
