How Long Do Koi Dealers Need to Quarantine New Fish? The Official Answer

By KoiQuanta Editorial Team|

USDA APHIS regulations require a minimum 30-day quarantine for imported koi, with extension to 60 days for KHV-suspected fish. This is the federal standard, and it's the baseline requirement regardless of what state regulations say. Some states extend this minimum. None shorten it for imported koi.

KoiQuanta's automated quarantine countdown timer prevents dealers from releasing fish before the regulatory minimum period has elapsed. The timer starts at arrival and alerts you at the 30-day mark, with flagging for any fish that triggered a KHV extension or other reason for longer quarantine.
