Hi, I have a question about QT tank, I had a sailfin tang in there with ICH, dosed with cupermine, and treated the fish, after 38 days in qt it was good and moved it to the DT.
About 3-4 weeks later the tank is still running, added top off water only, no water changes.
It's a 10 gallon tank
Can I add a new fire fish to the QT, or do I need to start the qt tank all over again?
