Hi. I have been having some problems with fungus in my 160 liter community aquarium. I have kept fish for many years at a time in the past, although I have never had serious problems with fungal growth. I noticed some fungus had grown on some wood that had put into the tank. It concerned me enough to remove this particular piece. All seemed well after that, however over the past six weeks or so, I have noticed that some of the fish in the aquarium have developed fungus growing on their bodies. IEVEN lost a few. I treated the tank with API Pimafix that contains Pimenta Racemosa (bay oil). The Pimafix didn't seem to help much. I Then started using tonic salt after water changes and dosed a cycle of 'wunder tonic' containing 1.5% methylene blue, 0.1% malachite green, 0.05% acriflavine and 0.04% quinine. I havn't had any further deaths since I dosed the wunder tonic product. Yet I am still somewhat concerned about the welfare of these animals, as two of my neon tetras and one of the bristlenose plecostomus have visible growth of fugus on their bodies. So my questions are what can I do now to prevent further development of fugus in the tank. As well as how to medicate or care for the fish that are still exhibiting signs of illness.
