IMO, quaranting just causes more stress. I personally never treat, nor quarantine. If an environment is in good shape, and if the fish is healthy, there should be no problems... And if there is ever an issue, like ICH for example, then again if the environment is healthy and the fish is strong, it should recover without any treatment.
Just remember the more you do to your environment and livestock, the more stress that is created. Best practice is to just leave things alone.
