Case Study: How One Hobbyist Stopped Losing Fish by Adding Quarantine

By KoiQuanta Editorial Team|

Sandra had been keeping koi for seven years when she contacted KoiQuanta. In those seven years, she'd lost four fish she was certain were connected to new additions: two deaths that followed a purchase from a new supplier, one death after a koi show, and one unexplained loss that she suspected was linked to a fish she'd moved from a friend's pond.

New-fish introductions without quarantine cause 85% of all avoidable koi losses in established hobbyist ponds. Sandra's loss rate fit that pattern almost exactly.

She started KoiQuanta in February 2023. By August 2024, eighteen months of zero introduction-related losses. Here's what changed.
