For the last few months I have had some Red Cherry Shrimp in an aquarium that was intended for Crystal Red Shrimp. I set it up with Aqua Soil Amazonia and quite a few plants and mosses. I keep the pH right around 6.0 and have some interesting observations for the Red Cherries!
Observations: - The Red Cherry Shrimp grow slower - Far less breeding activity observed - Berried females have become more rare - Life span seems shorter
If you have any observations of keeping Red Cherry Shrimp in water with such a low pH please feel free to share them!
