This sounds like whitespot and there are many cures 
available at the pet shop.  What is your water temperature? 
You should raise it to at least 82f both for the Rams which 
like warm water and also to help with getting rid of the 
whitespot. 

The parasite which causes it has a shortened life cycle in 
warmer water.  They can only be killed when they leave their
host to multiply in the water and the time between them 
doing this is shorter in warm water so they will therefore 
live less time on the fish.

hope this helps and you manage to cure it,
Ken.
