So within the last two days I've has a white fungus attack three of my fish. One huge khuli loache and a juvi payara. I've cleaned the tank, taken all wood out and furniture. I've cleaned the fake furniture and put back into tank, have cleaned the sand. Cleaned the filters, practically cleaned everything. Well today another loach died with fungus all over it. I'm worried my fire eel is next!!! What do I do. I'm trying api pimafix, and still having fish die. What's going on???
