On Saturday I did my weekly water change and did a partial rescape if my 9.7 gallon. Just moved some dwarf lotus to the back and crypts to the front. Between then and now (Monday evening) it seems my cherry shrimp have disappeared. I can only locate one of about 15 in the tank now. I also see some evidence of dead shrimp in the tank. This is not the first time I've seen a die off after doing cleaning and replanting. What's the trick here? Do you take your shrimp out of the tank when you do even a partial rescape? Granted it's only a 9.7 g tank. Maybe if it were bigger would things be a little easier and less sensitive? I'm sick of losing livestock especially when I'm so attentive to it and the hobby.
