Why is my goldfish turning red?

Why is my goldfish turning red? Usually, Goldfish develop red spots and splotches because of poor water quality. Even if it ends up being a bacterial infection—it is likely the water quality that caused the infection in the first place. Usually, water quality goes south because the fish are not kept in a larger enough tank.
