And.... Ich can live in a reef tank for a very long time w tangs fighting it off just fine... But in my tank I like it 100% ich free and I hope To keep it that way.. My Achilles is strong as ever never, had ich in qt then hypoed... When you have more fragile tangs and can keep them long term that's when you probably know a thing or two.. How many of you commenting in this thread have an Achilles in your tank ( just out of curiosity)
Anyway.. Double check ich life cycle.. A fish rubbing itself on a rock can be anything from ich to flukes.. These threads are made to be educational... If someone is wrong or does not agree you can post links to your argument or be a gentlemen.. I know that's hard for most people that are lacking in life I guess..gotta make up for it on a saltwater reef forum.. All the best..
