So I found 1 of my ps. Saulosi female 2 days ago on her side breathing But Not moving but her side fin I thought maybe she Ram in to the glass and stunned her self so I tried putting her by the filter. And so that didn't work so I put her in a tank by herself to see if she get better and the next I found her dead.
What killed her? Every one else in the tank is healthy and my water is fine. I have never had this happen before.
