Tips and Tricks
So, assuming you already have the physical pond ready to go (if not, click here to be taken to our comprehensive, step by step guide to building your own koi pond at home).
Let’s discuss what to do once everything is ready for your fish and the water has been properly cycled.
1. Careful Introductions
When introducing koi to a new pond, it is important to let them acclimate and stabilize before dumping them straight in.
You need to quarantine them in tanks that are at a volume of around 50 gallons per three fish and gradually introduce pond water to their holding water.
It is important to note that this holding tank must still have adequate filtration.
Add tiny bits to the water until around half is pond water. Do this over the course of a few days.
Once this is all set, place your koi in plastic fish bags and let them float for at least thirty minutes to acclimate to the water temperature.
This step is vital, as it helps prevent shock from the temperature change.
2. Feeding the Koi
After they are in their new pond, give them a day to rest then try offering food.
Add about what seems reasonable for them to eat within five minutes and scoop off any leftovers after their feeding frenzy has subsided.
Do note that if they are not fully adjusted to their new pond, they may not eat.
This is okay but by the third or fourth day they should be eating.
If not, you may need to troubleshoot your pond because something is stressing the koi.
Proper filtration for your pond is absolutely vital to your fish’s survival and longevity.
Fish without proper filtration are not thriving, they are surviving.
This is not fair to the fish, so if you are looking for a place to invest, filtration is the spot to do it.
Be sure to get a filter that supports both cleaning the water and promoting the growth of beneficial bacteria.
There are many options, of which you can learn more about here in our best koi pond filter options guide or in one of our other more in depth guides.
UV lights and other extras may assist in keeping your water clean and clear, especially if you are having problems with algae overaccumulation, so be sure to check out features like that while you are filter shopping if you have any concerns.
4. Water Quality
The quality of your water is perhaps one of the most important things to keep in mind.
Aside from filtration, you must also ensure that the water is the correct temperature and properly shaded.
Koi like shady areas and do not do well in overly sunny spots, plus algae will overgrow if the pond is overexposed to the sun.
In general, the koi like their water to be at around 65 to 75 degrees fahrenheit but can tolerate some deviations.
They are generally very hardy fish but still deserve proper temperature regulation where possible, as it helps them be happy and healthy.
5. Safe Decor
While you may see koi ponds with striking angular rocks and embellishments, this is not a good practice.
Koi are notorious for digging and rubbing against their enclosures.
Having sharp rocks or other pieces can cause serious injury to your fish, resulting in infections which can then spread to the other fish in the pond.
Opt for smooth, rounded decorations and rocks when making your pond and be sure to regularly check them to ensure no breakage has occurred and no sharp objects have fallen into the pond.
Caring for koi is surprisingly easy if you plan well before starting the process.
They are very hardy, durable fish that can survive a lot, so they should do well under most care.
Try and strive for the best possible balance of temperature, water quality, and food and you will be rewarded with years of stunning, vibrant koi accenting your yard or space.
