My question is not related to human disease. My question is related my heartiest Discus fishes. My Discus fishes have been suffering from Mouth fungus and cotton body(cloudy peppering) also swelling and cloudy eyes. They are not willing to feed anything and standstill just at the corner of my Aquarium.I use Paraxin 500mg for my 4"x1.5x1.5 aquarium.Besides this I use Teramycin 500 mg and Metrozil 400 mg and Non-Iodized salt. But till no recovery has been done. I am really confused. Please tell me what should I do?
