Red orb on stromb

[Peach02]

So I've had this snail (stromb snail / fighting conch) for about 2 weeks now and he is very active virtually always 'hopping' around the tank or burying himself or hiding in his shell from hermit crabs eating the alge on his shell. This evening I noticed a red lump on his mouth about 2x2x1mm and am worried that it is a parasite or virus. (Sorry for bad photos)
Does anyone know what this is and how to treat it?

I don't know what it is, but if it was a parasite I would think it would be on the conch's flesh not the shell. I'm sure someone may know.
