14 days, 45 days in QT I thought about going longer but with one fish, eating, and looking healthy I didn't see the need. I am a firm believer in QT and proper pest controls. I have more experience with coral (pests) than I do fish and I've been lucky to dodge anything in my original nano tank. That aside my bigger tank is newer and I don't trust LFS to do any type of proper QT... so all the original fish went into QT following similar guides. Shockingly my fish that have done the best are from Liveaquaria's divers den... I know that's been hit or miss since the Petco merger, but I think the Wisco facility is better run than the LA.
Coming back to this thread
@Mr.Weathers if the spots come back if you can snap a shot. I wouldn't recommend putting the fish into the tank yet until you are totally sure of what it is... Ich can reproduce and cycle itself without you being aware.
