So I scoured the earth (ok just my corner of it) and finally found an LFS that had exactly 3 cherry shrimp. So I bought these elusive suckers at a ridiculous price and brought them home. They are juvenile, at least 1 was definitely a female and the other two were unknown. I've had them about a week and 2 of them have perished already. The third one has developed a saddle so I know I'm left with 1 girl. The problem seems to be molting. I check on them every night and both the dead ones I found in the morning (on different days) on the bottom of the tank hunched over with a white/yellow band around their middle. I am assuming they tried to molt during the night and didn't make it out of their shells. I have since done a massive water change, before I had about equal parts distilled and tap water. I was thinking my tap water was too hard and that was the problem? I added way more distilled water so it's about 15-20 percent tap now and the rest distilled. I have no idea if the 1 I have left has molted yet or not, as they like to do it while I'm sleeping. I think she looks bigger but that might just be me. If she hasn't already I know she will soon and I don't want to loose the last one. Is there anything I could do to ensure her survival? I don't have a testing kit yet, I plan on buying one the next time I go to the city. I live in the stix and the closest LFS to me is almost an hour away. Anything I could do without having to run out and buy something would be a great help.
