Hello,
Truly sorry to hear about your problem. I was looking through your past threads about the "My inside ray tank" and I found this picture.
Unfortunately, that ray's gills looks highly irritated. This could be an existing problem back in '07 that was never corrected and only escalated. It seems like it could definitely be something wrong with your water. I was check for GH, PH, and other water chemicals from your area (chlorine, chloramines, etc). Even if you are using well water, leeching of chemicals can occur and often does.
Best of luck!
