mouth disease?

Can anyone tell me what is happening to my red jewels mouth and if its a disease how I should go about curing it...thanks.

Looks like mouth fungus, easily treated with meds from your lfs

It looks more like the skin is peeling off exposing the white colour underneath rather than an external growth though....can mouth fungus look like that?
