Hello, I am Goldliocks and I live in Spain. I have a very sick goldfish who is lying on the bottom of the tank and only swims now and again with difficulty, he now has one eye that is much larger than the other, I have put a dose of Epsom Salts in the tank together with a dose of Bicarbonate of soda. the dose was as advised by one of the fish websites. I have been to look at Charlie the goldfish this morning and to me he does not look any better. I am really worried about him for I do not want him to die. I would be very grateful for any advise I can receive to help him. I have asked my vet here in Spain but he does not know anything about fish at all. Please help I am desperate.
