Recently I've had a fungus issue in my 20 gallon long, which I only set up a few weeks ago. My dwarf gourami, who came to me injured, now has fuzzy white fungus growing from his wounds. I've been treating with an imagitarium brand antibacterial/antifungal remedy, half doses every day rather than full every other day, since I have snails in the tank. I've also been giving the gourami 20 minute dips in water in the high 80s, with a little iodine free salt in it. He freaks out and breathes quickly when I do this, but it makes the fungus fall off (Only to grow back later, it seems.) Today, I'e noticed what looks just like the same white fuzzy fungus he has growing on my driftwood, and clumps of white fuzz and debris all over the tank. I'm not sure if I should try to vacuum it out or not, as I'm afraid of water changes messing up the course of the antifungal. To make matters worse, I had a recent ammonia spike I'm still dealing with! I have no clue what the best course of action is right now, or how to get my tank clean. Any advice?
