I noticed a few days ago that my angel fish, who lives alone in a 30 gallon tank, was looking really gross all of a sudden, she had gross scaly stuff on her face, and her fins had got all clumpy together, her tail fin has a huge hole and black stuff around it, so I thought it might be fin rot. So I've had her on Lifeguard meds for 3 days, since it works for a whole bunch of stuff (fungus, ich, fin rot, bacterial gill disease, etc). These meds worked amazingly for her before when she had ich, but they aren't doing anything now, and just now she's taken a turn for the worse, suddenly has no energy to swim, so the current keeps pushing her down onto the gravel. She looks like she might die soon. I'm at a loss of what more I can do. But just yesterday she was fine, although her fins looked gross, she still was swimming around and had an appetite. She's breathing okay, not rapid breaths like when she had ich, but right now she looks very lethargic and tired. I can't take a good picture because I can't get close enough to her.
