Hi, thank you for your reply. I am currently using Imagitarium Parasite Remedy. I got it from Petco last minute, I know there are some other good stuff out there, but it was the only thing I could find. Fortunately, the fish seem to be responding fairly well after 2 treatments. I changed at least 30% of the water before adding the remedy solution, hoping to get rid of the exisitng tomont.
I'm wondering, if I do exactly like you said, quarantine the new fish for 4 weeks before adding them to the main tank, will I still have a chance to get Ich in the future?
Thank you!
