Hello, three weeks ago I had an outbreak of marine velvet and lost most of my fish. I'm left with just my inverts as well as a yellow coris wrasse, a foxface and a blue hippo tang that I assume are resistant to velvet, they currently look healthy and don't have any symptoms. I'm considering removing the fish to a separate tank to treat them with copper and let my display go fallow for two months. My question is whether it is really necessary to remove the resistant fish and fallow the tank. Can the velvet survive in the tank with only the resistant fish?
