Looks like a lymphocystis viral growth, an injury, or the start of a
Columnaris infection. Both of those often start at the mouth. I
think it looks more like lymphocystis. Lymphocystis is a viral
disease that can cause tumor-like growths on fish. There is no cure,
but the virus and associated tumor often goes away on its own. It
can take a month or more for lymphocystis to clear.

If you have a quarantine tank, move the fish there because it will be
shedding virii. Supposedly 3 hour acriflavine baths every few days
will help clear lymphocystis and will certainly help with Columnaris
or secondeary infections. Treat in a separate container - a clean
bowl or dish with an airstone is fine for 3 hours. Acriflavin stains
so don't use your favorite Ttpperware. Watch for signs of Columnaris
in case I'm wrong. Those are white, fluffy finrot, white patches on
the body, and reddened fin bases. If that happens, feed antibiotic
food and put kanamycin in the water immediately. If the fish refuses
food, add furanace to the water as well IF the fish is in quarantine.
Furanace is bad for biological filters.

If you don't have a hospital, do not allow the fish to die in your
display tank. You must euthanize a lymphocystis-infected fish if it
looks close to death to keep the disease from spreading.

Sheesh...yet another way long post. I gotta work on that old disease
FAQ some more. ;-)
