I have some red cherry shrimp in straight treated city water. They seem to do fine, good color and breeding.
I had some Mischling shrimp in a Walstad style shrimp bowl. They lasted about 3 months. I also tried some CRS and they all died pretty quick.
From my experience RCS are the only ones that can handle our hard, 8.0pH water. I would be interested to see if anyone else has some input.
