What would qualify as one? Does it need a filter, gravel, and other things to make it a "home?" How often and how much would I need to change the water in it? (I wish I could leave him in his cup and do daily water changes until he can be added to the tank, but that doesn't seem fair)
I would float the new fish in containers/cups in the big tank for at least 2 weeks.
If you don't quarantine them, one of them could come down with sickness and you will have to drain your tank, re cycle and deal with sick fish at the same time. It might not seem fair but exposing them to each other can end badly, and ruining a cycle you worked hard to achieve is no fun either.
A QT tank does not need a filter, and shouldt have gravel.
You don't want gravel because a bare bottom tank will make it easier to see if he's pooping regularly and if his poo is a healthy color. Water changes will depend on the size of the container.
Basically the most important thing with QT tanks is to have a way to heat it and doing proper water changes.
