We recently purchased 2 goldfish and they came down with ich. I researched it and it said it was very common most goldfish get ich from the stress of being introduced to a new enviroment. They're recovering nicely (they have a much bigger tank since the last time i took pictures) and they seem very happy. The bigger one, however, (a little over an inch long) isn't eating as much as the little one but he is eating again. should I be worried or just wait until the ich is completely clear?
