Just like to give an update. My yellow Cichlid with the white pectoral patches on fins. Well for the past week his white patches went from white to grey and now black. Looking closely the patches are actually gone and I’m guessing the black is basically scar tissue or dead cells on the fins. Not sure what medication worked or if it was just time. Either way a couple more weeks in the QT tank and he might be able to join the community. However, I just noticed two of my other cichlids have fungus growing on mouth and fins. I don’t understand, I do water changes sometimes twice weekly, my parameters are perfect, not overfeed. I just don’t understand how these issues keep popping up.
