I do biweekly water changes and I went to do mine today and I noticed a spot on my clownfishes head. No other spots of ich. I’m not sure if I should leave it and let it fight it off on it’s own like some have said in threads I’ve read, or treat it and my others in a quarantine tank. I’m afraid if I leave it in my dt I’ll have dead fish, and if I quarantine they’ll all die anyways. I’ve never had good treatment experiences and I’ve only been in the hobby a little over a year. Advice would be great!
