Should I Continue Treatment?

[ED10]

Hi all.
Yesterday evening i noticed one of my cories had a small bit of cotton wool like fungus around its mouth, this had progressed into covering its entire mouth by midday today.

I went to my LFS and they gave me some pimafix to add to the tank.
I added the first dose but unfortunately the cory died this evening.

My question is, should i now continue or stop the seven day dose of pimafix?
No other fish show any sign of fungus and all my water readings are perfect.

Thanks in anticipation.

It wouldn't hurt to continue dosing the tank, especially since pimafix is a natural extract. I would continue to do it just to be on the safe and to make sure all teh fungus is gone is truly gone from your tank.
