Unfortunately, the remaining fish didn't make it.
I gave 3 doses of the Quick Cure. The first at 50%, then 75%, then 100%. I didn't even notice a difference; not that it got worse, but didn't get better. I think that the Maracide worked better, as I could see the fuzz almost totally gone after one 100% treatment.
Moving forward, is there anything that I can do to make sure that this fungus isn't in the tank for the next inhabitants. I'm hoping to use the tank for more Channa, but probably a different species. Obviously, I don't want to have to deal with this fungus anymore.
Thanks.
