Hi! I am new to this forum and glad to be here!
A couple of weeks ago, I noticed that one of my panda cories was breathing rapidly and not eating. He was the only fish behaving this way. Since my water tested okay (current parameters below), and I read that rapid breathing can be a sign of gill flukes, I thought perhaps that was the problem and treated the tank with ParaCleanse (metronidazole and praziquantel). You treat one day, skip a day, then treat a second time. Both times, the day after the treatment, he seemed much improved, breathing normally and eating. After the treatment ended, he did well for a week, but now he's back to breathing rapidly and not eating again. I treated the tank yesterday, but he is still breathing rapidly so far today.
I'm unable to take photos, but I don't see anything wrong with his body or fins. Since he improved after each treatment during the first round of medication, I figured the medicine was helping, but now this most recent time, it hasn't made a difference, so I'm not sure what's going on.
Does anyone know what could be wrong?
Water parameters are: Ammonia 0, GH 60, KH 80, pH 7.0, nitrites 0, nitrates 20. Temperature is 76.7 degrees Fahrenheit.
Thanks in advance for your help!
