Quarantining fish if suspect tank already has ich

[Trigger Man]

I used to QT any fish that looked like they had any sort of disease, being that I have reef tank (a pain to try to catch a fish once in there) and my other fish like to bully the newcomer. As of late though I've been just adding my purchased fish into my display tank and if Ick appears I found No Sick Fish Ick medication has worked well for me.
