Sounds like you just put the fish in observation rather than really proactively quarantine them. By my definition of quarantine (for marine ich), you need to use one of several proven ways of eradicating marine ich, like hypo/copper/tank transfer/chloroquine phosphate.
Since your tank is a fish only. It will be easy if you decide to treat ich on the spot.
And I can't stress enough of quarantining all your fish in general. There are stuff out there that are more dangerous than marine ich if you don't quarantine your fish. You don't want to loose all your fish, especially if you have a tank full of fish you have collected over the years.
