Hi there, im really worried about my Shubunkin. He has Popeye so we got treatment for this - Melafix, Antibacterial remedy - the instructions said to use it for 3 days, which we did, but it did nothing. Now he is really ill, very lethargic, he isnt eating, is in a really quiet part of the tank. His fins are just floppy down his sides, they arnt even clamped to the sides of his body, as if he cant even do that. He is off colour too, he isnt looking his usual golden self, but quite pale. He is opening and closing his mouth very slowly and his rocking side to side. I have also noticed tiny white spots on him, head and body. We have done a water change, we were worried the remedy we got him for his Popeye could have been the reason so wanted to get this out of the water, his pumps and filters are all clean, but the water change does not seem to have made a difference. We have other fish in the tank with him, but they are all ther're usual chirpy selves, like he is normally, please help!!
