Does the patch on the fish look like cotton wool?
Check the patch for any red areas?
Does the white patch look like bleaching beneath the skin?

 

[TekFish]

The patch does look like its beneath the surface yes.

[WILDER]

Bleaching beneath the skin can be columnaris.
Have you noticed any fish flicking and rubbing?

What is your location to suggest a medication?

 

[TekFish]

I haven't noticed any flicking or rubbing, and I live in the UK.
