All- Since I moved from City water to Well water some of my fish will get clear patches where it looks like the pigment goes away... Otherwise all seem healthy and it eventually goes away. All my water parameters are good. I think it must be something in my well water. I have had it tested and nothing is abnormal. My tanks have been are established-10+yrs. If you can identify this please let me know.... Please see the photo of the small green terror with this condition .
