Have a mystery snail who has had a few light white spots on him in the past, a couple months ago, which went away. Now he has a bigger cottony looking spot.
A friend gave me some fungus treatment (Tetra Fungus Guard), but am nervous to use it before checking with others.
Of course snail is my favorite. So really hoping he'll be ok
