hi,could i ask a question about my fantail goldfish? I know he has swim bladder disease and was a floater, so i treated with brine shrimp, peas, and extroaordinary water quality. Now the fish has been sitting on the bottom of the tank for a week now, pretty lethargic. I have to hand feed him now. He eats peas/shrimp, etc but it looks like he cant swallow the food. I see it it his mouth for a long time like hes trying to digest but he eventually spits it out. I am going to set up a hospital tank, but I have no idea what to treat for. Bacterial infection, parasites, there are so many possibilities. Is there an overall drug that would be my best bet?
