I’ve decided to go fallow after an ich outbreak in my 90. I have a 60 gallon qt set up for 9 small to medium sized fish, (2 wrasses). I am going to treat with copper power and was wondering if it would be better to add copper after I’ve got all the fish in qt or add the fish into 1.0 ppm? I’m thinking it might take a while to catch all the fish. Any other advice on going fallow and qt would be appreciated as well, especially anything regarding wrasses as I know they are more sensitive. Thanks
