I have a 30 gallon freshwater community tank consisted of 10 rasboras, 3 cories, 2 rainbowfish, 2 german rams, 1 bristlenose pleco, 1 oto, and 20 ghost shrimp. The tank is moderately planted. I noticed that my German Ram has several white spots on its fins, which appear to be ich. How can I treat the tank, or the infected fish, without harming the sensitive fish, plants or invertebrates?
