Calgary Stores, Stocking Questions, and preparing my tank for Mandarins

That time frame assumes no fish at all, sick or otherwise. Adding new fish, even after quarantine, will likely result in one or more getting ich, starting the whole process over again. If you're going to quarantine, get the existing fish out, add them all to QT, treat for ich, and after waiting 10 weeks, add them back. Or don't waste time QT'ing the new fish and hope for the best. Which, IMO, is a bad plan.
