Saves fish. Exposed parts turn blue for a few days. amazing things. Sick leave for 5 days with this material alone, and the fungi disappeared. Protect your clothes and walls - it's quite blue but stained.

I still had fungus on many of my eggs. Will try again with the…

I've been using methylene blue for a long time. I use it for fungi on my fish when I notice them starting a little or when their fur is starting to get a little slimy.
