This may be a dumb question from someone who has been in the hobby for about 2 years, but I bought a Sailfin Tang for my reef tank. I decided to quarantine him after having some bad luck with the ich on my last tang.

Being the first time I've ever quarantined anything (I know should have started sooner), but how long is long enough to QT ? I've read 1 to 2 weeks

He's been in QT for 4 days and I'm anxiously waiting to drop him into the display.
