I have a bicolor angel he’s about 5 inches and a melanarus and cleaner wrasse (blue line) who are both about 3 inches….I have read they are sensitive to copper, but I hate to be that guy but I’ve worked really hard to risk ich or velvet in my tank…. so how would you go about dosing cupramine I know it says 20 drops per 10.5 gallons first 48 hours. So if I break that down to take 7 or 8 days instead would that be better and more likely to not harm the fish since it’s so much slower? for example instead of 40 drops per 10 gallons over four days dosed twice I would do 2 drops every 12 hours for 5 days. The fish arnt sick this is just preventative, thought I finally had the qt protocol under wraps but these fish weren’t cheap and apparently sensitive to copper so I’m asking the experts haha. Any advice helps and also helpful alternatives if there is any that treats for velvet ich and gill flukes like cupramine does I’m willing to try that if it’s not outrageously expensive/hard to find.
