I have been struggling with fin fungus on my tattered golden angel for over a week and a half. Now I have spotted a white spot on a coral platy female. The spot is in the centre of her tail fin and now has developed in to a hole with a white ring around it. Are there any ideas on how to fix? 
For the fin fungus I have been using "fungus eliminator" and doing water changes as instructed.
