There are a number of medications available in the US specifically for 
fungus.  Where you are I do not know.  I would listen to the LFS shopkeeper.

Fungus is "opportunistic", which means it is always in the water, waiting for 
a fish to become weakened by injury or stress.  Two big forms of stress are 
poor water quality and long transits, like from Venezuela to Asia.

South America.

Maybe.  Slowly elevating it until you have about 6ml of salt per liter may 
help the fish fight it on their own.  But try the medication the LFS
