What a disaster.... I woke up to all of my 10 angelfish gasping for air. Prior to this...I have been dealing with what I think is a type of fungus, their pectoral fins have been shredded and have white cotton looking patches on them. I cleaned the tank and filter media on Saturday, removed the carbon filter and medicate with maracyn. I medicated the entire tank (3 packs for a 30 gallon). I noticed my water being a little cloudy but just thought it was from the medication. I completed two doses so far (Saturday and Sunday) and this morning (Monday) I noticed all my angles have inflamed gills and redness where the body connects to the pectoral fins. This symptom was not present yesterday. This time I dosed with ick x because it helps with fungal infections as well as another round of maracyn. I never have ammonia spikes because my tank is over 3 years old and I just did a 25% water change on Saturday however, I did check for ammonia (of course after I medicated) and it's .25 ppm. I did an emergency water change. A few went belly up, so I moved them to a bucket that is being filtrated. I haven't medicated again since I did so this morning before I did an emergency water change, i know I know i know... it doesn't make sense. They were fine last night at 2 am when I was done working in my study. I'm not sure what is going on.
So, I guess my question is.... what caused this... The medication, the fin fungus, ammonia? Do I continue medicating?
