I have recently discovered ich on several of my fish in my main tank. However the only tank I have available for quarantine is a 10G so with that being said I'm going to have to keep a lot of fish in my main. However I fear that they will get ich in the process and I believe the risk in turning that tank's temp up to 85 and using salt treatment is much to high considering the amount of time and money put into several of my fish. I would like to know if there is any alternate treatment for my main tank. At the moment there are no more fish with ick in the tank.
