sorry it's been a long day. If you wanted since a qt
fish should be left 3-4 weeks in the tank until put into the main you could set the main up left it cycle and a week into the cycle set up the qt
and let the fish live in the qt
until the main has fully cycled. Only add one fish to the qt
though something hardy as well since once your tank is done cycling the beneficial bacteria wont be strong enough to support a large bioload.
