Goldfish-large red patch on side
There is a 20 gallon aquarium in my office with 5 goldfish in it, 4 orange, 1 black (if it matters). One of the orange goldfish recently developed a large red patch on it's side, and it's starting to look a little white in the center too. I have attached photos, let me know what you think it is and how it can be treated, thanks!
