It doesn't sound like a parasite to me.  The glass isn't the most usual
place to find a parasite.

You might have limpets.  Small limpets can be clear but their shells are
calcite, not silica.  The ones I had in one of my tank got up to about 3
mm and changed from clear to white as they got older.  They proved to be
completely harmless algae grazers.

The limpets eventually disappeared, and I kind of miss the little guys.
