Setting up a QT tank cost barely anything. All it takes is a ten gallon plastic tote, cheap 50w heater, sponge filter, cheap air pump, and a few pieces of pvc. Why in the world would you not spend $30-40 dollars to keep from losing $100 in fish. I QT all fish and treat with CopperPower. The only excuse not to is laziness.
