5 Things you should never do to your koi fish

1. Don’t overfeed your koi fish.

The amount of food your koi need will vary depending on the time of year and the water temperature. In general, you should feed your koi 2-3 times per week, and each feeding should be limited to the amount of food that the fish can consume in a few minutes. Overfeeding can lead to water quality problems and may even kill your koi.

2. Don’t use harsh chemicals in your koi pond.

Koi are very sensitive to changes in water quality, and the use of harsh chemicals can be deadly. If you need to treat your pond for algae or other problems, be sure to use a product that is safe for fish and follow the directions carefully.

3. Don’t allow your koi to become overstressed.

Koi are delicate creatures and can easily become overstressed. Too much noise, bright lights, or even too much handling can all lead to stress in koi. If you notice your koi acting unusually, it may be a sign of stress and you should take steps to reduce the stressors in their environment.

4. Don’t neglect your koi pond.

A koi pond is a big responsibility, and it’s important to keep up with regular maintenance. This includes cleaning the pond, testing the water quality, and providing adequate filtration. Neglecting your pond can lead to serious problems, such as sick or dying fish.

5. Don’t release your koi into the wild.

Koi are domesticated fish and are not well-suited to life in the wild. Releasing them into natural bodies of water can introduce disease and harm native wildlife. If you no longer want your koi, the best thing to do is to find a new home for them with someone who is prepared to care for them properly.
