In addition to the issues with my clown loach. I noticed today that my opalline gourami which I have had for 6 mths either seem to be loosing color or scales. See attached photo. Again all my water levels are fine. This only thing I can pin point to is the Ich medication I used yesterday and today I notice the change.
Should I now put back the carbon filter to remove medication from the water?
I did do a 20% water change before posting this.
Help....
