I had a pair of mollies who had this, which i thought was whitespot. It turned out that after 6m of treating them, it just wasnt budging, and i ended up putting them to sleep. Seems it was columnaris If you havent already, separate them.

I've had this problem with mollies in the past, atleast it looked the same. This was a very long time ago. The explanation I got from my lfs was that they keep their mollies in brackish water and I was trying to keep them in freshwater. I don't know if that was the real reason or not, but when I started keeping them in brackish water, they did much better for me.

Mollies are true brackish fish, try making a 10 gallon tank into brackish and keeping in there.
