Quarantine tanks are very important in this hobby. They don't need to be big, maybe 10-20 gallons for most fish. They are very easy to keep. This is all you need for one.
RO/DI Water
Fish Net
10+ gallon tank
something that circulates water
over the back filtration
These are great for treating sick fish and ridding them of any disease that comes along.
