its not ich, already been through that this year. Ive never had any with parasites, but thats the only thing i can think of, its just one spot the size of a pencil eraser near her top fin. I treated her with parasite tablets as soon as i saw it pop up. i admit i wasnt at home for a week to take care of them as needed and they didnt get there weekly 25% water change. i dont know how she got it but the other fish in the tank is clear and bright. And besides the one white spot, there are no other symptoms i know of yet. she look fine, appitite is same, swimming fine, looks clear and alert. Someone please repond with some sort of suggestion, it looked nothing like any of the sympotoms on the back of the boxs for fungus, parasited, ich and there was one more i thought, but anyway, your advise would be greatly appricicated.
