Hi Everyone,

Just wondering if someone could tell me what the possible cause of a white
patch on my goldfish is.

Have had 1 goldfish and 2 smaller fish in freshwater tank for 7 months. No
problems at all until this week.

On thursday white patch appeared near the head of the goldfish with red
around the outside of it. Since Thursday the patch has nearly doubled in
size, there is an area of redness around the white.

Ph is fine, the other fish are fine does anyone have any idea of what this
could be?

Many thanks,

Aus Wendy
