Ideally it should be a complete system with wave maker and filteration ect.. but I know it can be challenging to have those for most of us.
What I did previously was QT the fish in a large blue Square tube with air stone and some filter media and doing a water change every few day. I also added small amount of Seachem copper to speed up the QT process.
After the QT period, I will add the fish in a tank divided section , where I will observe for any fish aggression and any ich outbreak.
