The corycats in my planted tank recently laid eggs. Unfortunately the entire
batch was lost due to some sort of white fungus. Can anyone here recommend some
sort of fungicide to dose my tank with the next time?

I have Telanthera Roseafolia, Amazon Swords, Corkscrew Valisneria, Sagittarita
Subulata and Rotala Wallichii all in the tank and am hopeful there is a product
that will be safe for these plants as well as the fish.

Thanks in advance -- Christine
