Yeah we have a total count of thirty shrimp, six per tank. And it was weird that we found them, I thought maybe the first one did die the day we were cleaning as I was taking out the plants to give them a clean, and maybe one secretly jumped off the plant and missed falling back into the tank. But then the next day after the water change, there was another one there!
Water temps were good. And quality of water was good also. However none have committed suicide since!
The few that were missing were eaten, but they still had some. Uneaten body at the bottom that we took out immediately.
