Why Should You Quarantine New Koi Fishes?

Before I tell you about the koi quarantine tank…

Let’s talk about the importance of putting new koi in quarantine first.

There are several reasons:

  • It gives your new koi enough time to rest and recover from stress. All that handling and transport is stressful to these colorful fishes, after all!
  • It lets your new koi acclimate itself in its new environment. A sudden change in the environment can be particularly stressful to koi, so it’s best to give them time to get accustomed to their new home.
  • It gives you time to make sure that your new koi don’t have diseases that could spread to your other fishes.


What’s Essential For The Koi Quarantine Tank?

Now that you know why it’s important to quarantine your new koi fish… 

Let’s talk about the koi quarantine tank!

To get you started, here are the important components of the koi quarantine tank:


Quarantine Tank

Of course the most important component of quarantine tank is the tank itself.

This should ideally be made of plastic, rubber, or PVC.

You don’t want galvanized tanks as they can be harmful to your koi.

Even if the quarantine tank is only a temporary dwelling for your koi…

Make sure that it is still spacious enough.

A 100-gallon tank, for example, can only hold up to four 10-inch koi.

Tank Heater

Koi fishes can survive under various conditions.

But for purposes of your quarantine period, you want to maintain certain conditions.

Try maintaining the temperature in the quarantine tank in the 74°-78° F range.

A submersible water heater should do the trick. 😉

Tank Filter With Pump

As with a typical koi pond or tank…

The water in your quarantine tank needs to be filtered and to circulate.

All you need is a powerful pump that can circulate the water in the tank every 30 minutes or so.

In addition, you need to set up a filter to make sure that the water is always clean.

Aerator For Tank

Unlike the natural koi pond setting…

There typically isn’t enough dissolved oxygen in fish tanks to keep the fish alive.

This is why you need to have a trusty aerator running in your quarantine tank.

Cover For Tank

Koi fish will try to escape from new environments.

So make sure that you have a weighted cover fitted for your quarantine tank.

Just to keep the koi from jumping.
