How and When to Quarantine Your Koi Fish
One of the difficult aspects of operating a koi pond is the quarantine system.
Of course, not everyone uses this system even though everyone should.
With koi fish living in your controlled pond environment, if one gets sick, they'll all get sick.
This means that one fish dying can be the start of the entire colony going belly up.
There are two basic principles you'll need to know if you're looking to operate a successful koi pond that will last for many years.
You need to know how to quarantine your fish properly, and you need to know why you should do it.
Starting with the latter, the "why" of the quarantine process, is a little easier to explain.
There are basically two reasons that you would attempt to quarantine your koi.
The first reason has to do with illness.
If you notice that one of your koi is looking a bit unspectacular, has bad spots, or isn't as lively as the rest, you want to get it out of the pond.
If it's ill, the sickness will spread to the rest of the pond.
Placing this fish in the quarantine tank will not only give you a better chance of saving the entire colony, but also allow you to attempt to save the life of the sick fish.
While the fish is in quarantine, you can start to feed it different types of food, as it may only be malnourished.
You can give it certain types of medicines for parasites and other sicknesses if it warrants it.
Regardless, it needs to be alone and away from the pack here.
The second reason you would quarantine has to do with introducing a new fish into the koi environment.
If the fish you purchased has any type of parasite, you don't want it spreading throughout the colony.
The chances are relatively low of a properly cultivated fish that was already quarantined, most likely, having a sickness, but the risk is just too great.
Your koi are a huge investment, and having them all die would be a disaster.
The new koi should be quarantined for a minimum of three weeks before introducing it into the pond.
It seems like a long time, but whatever illness the koi has will affect that fish and let you know it's there in that amount of time.
If it's okay after the three weeks, then you can place it into the pond without worry.
Now, let's talk about the quarantine itself.
The reason most people don't have a quarantine tank is that they take up a lot of room, require a lot of work and will cost a lot extra.
At a minimum, your tank should be 100 gallons.
It also needs to have the same stellar filtration that you pond uses (mechanical and biological).
The water has to be controlled and heated to at least 70 degrees, and the levels have to be just as pristine as they are in the pond.
This means that you have to check them repeatedly.
Also, you will have to cover the quarantine tank.
Koi like to jump in an environment like this, and you could wake up one morning with your koi on the floor.
If you handle the quarantine correctly, introducing new fish and separating the sick ones until better should be no problem at all - just a little more effort to keep your colony thriving.
