There are several factors that affect a Koi fish’s survival ability.

Read on to find out more about Koi fish and their eating patterns.

Factors Affecting Koi Fish Feeding Schedule

Below are some of the factors that impact the feeding schedule of Koi fish.

Water Temperature

One of the most important factors that will affect how often you need to feed your koi is the water temperature.

In cooler water temperatures, koi will have a slower metabolism and will not be able to eat as much as they would in warmer water.

As a general rule of thumb, koi should be fed once a day when the water temperature is below 50 degrees Fahrenheit.

When the water temperature is above 50 degrees Fahrenheit, you should feed them two to three times per day.

Water Quality

Another factor that can affect how often you need to feed your koi is the quality of the water in your aquarium/pond.

Koi fish are very sensitive to water quality and can become sick if the water is not clean.

It is important to test the water in your Aquarium regularly and take steps to improve the quality if it is not up to par. If the water is contaminated, you may have to restrict their feeding schedule.

Koi Size

The size of your koi will also affect how often they need to be fed.

Smaller Koi fish will have a faster metabolism and will need to be fed more often than the larger ones.

Experts recommend that Koi fish should be fed once a day when they are less than 10 inches long and two to three times per day when they are more than 10 inches long.

How to Check if Your Koi Fish Is Properly Fed

There are several ways to check if your Koi fish is getting its proper nutrients. Koi fish, themselves, will exhibit signs if something is amiss.

Lethargy

One of the first signs that your Koi fish are not being properly fed is if they become lethargic.

If your Koi fish are swimming slowly and not as active as they normally are, it could be a sign of low energy levels.

In that case, you will have to switch up their dietary pattern.

Behavioral Changes

Another sign that your Koi fish are not being properly fed is if you notice changes in their behavior.

If your Koi fish seem listless, uninterested in their surroundings or otherwise behaving erratically, it could be a sign that they are not getting the nutrition they need.

Weight Loss

If your koi are losing weight, it is a sign that they are not being properly fed. Koi should be able to maintain their weight with a proper diet.

If you notice that your koi are losing weight, you will need to increase the amount of food you are giving them.

Changes in Appetite

If your Koi fish seem to have a decrease in appetite, you may need to check up on that.

Koi fish are generally known to have a voracious appetite and will eat whenever they are offered food.

If your Koi fish are not eating as much as they normally do, it is possible that something is wrong.

Swimming Near the Top

Another sign that your Koi fish are not being properly fed is if they are found swimming near the top of the aquarium.

Since oxygen levels are higher near the surface, your Koi fish may be attempting to get as much oxygen as they can.

This can be caused by a number of factors, including a lack of food. If you notice your Koi fish swimming near the top, you will need to increase the amount of food you are giving them.

Koi fish typically swim in the middle or bottom of the aquarium. Be on alert for any Koi fish swimming near the top as it is one of the surefire ways to know that something is wrong.

If you notice any of the above-mentioned signs in your Koi fish, it is important to consult with a qualified veterinarian or Koi specialist to determine the cause.

In some cases, these signs could be caused by a medical condition and not by a lack of food.
