So I bought a blue powder tang and it’s been quarantining for about a month in one of my friends tanks. My friend noticed that it began to show signs of ich and we started to dose copper power at 2-2.5ppm and will do about 70days of treatment. What I don’t understand is that once the ich problem is gone, what stops it from returning once I transport the fish to my DT? Will stress from the move make it return? Only about a 15in drive.
