I have had 3 fish in quarantine for 3 weeks now and just noticed one of them has ich. I purchased medication called Nox-Ich that has malachite green in it. The guy at aquarium store said to add 10 drops a day for 3 days and turn the heat to 82 degrees. Does this sound about right? Never dealt with ich before so I am clueless . Wanted to check here before doing anything.
