I recently started the hobby and lost my pair of clowns due to velvet, I made the mistake of not quarantining and will never make it again. My question is do I have to quarantine incoming fish in a established tank? I just got a quarantine tank and am setting up I intend to treat incoming fish with seachem cupramine( if you have a different opinion on meds please express it). I’m going to leave my dt without fish for 45 days maybe more so the velvet can clear out. But I also want to quarantine my fish at the same time so once the 45 days is up I can introduce them. However because I just got a qt and it is not cycled I’m not sure if that would be safe for the fish?
