If the pond is not deep enough, you might want to consider adding a pool or another layer of water to it. Another possibility is that the fish are not properly acclimated to the pond.

If the fish have never been in the pond before, they may not be used to the water temperature or the environment. If you are not sure what is causing the fish not to move, it might be best to take them out of the pond and bring them back when they are more acclimated.

Koi are tropical fish and as a result are not typically active in cold climates. Additionally, many people keep their koi in small, stagnant pools that do not provide them with the necessary oxygen and movement to thrive.

  What Color Should Pond Water Be?

If your koi are inactive, there may be a number of reasons for this, including:

1. Poor water quality – Koi require clean, oxygen-rich water to thrive. If the water is cloudy or has debris, it will not provide the necessary nutrients for your fish.

2. Lack of movement – Koi are often kept in small, stagnant pools, which limits their ability to move and explore. Movement is key for a fish’s health and well-being.

3. Lack of sunlight – If your koi are kept in an area without direct sunlight, they will not be able to get the necessary amount of sunlight to produce energy.

If you are unable to determine the source of your koi’s inactivity, it may be helpful to bring them into a fish store or aquarium specialist for a check-up and/or adjustment of their water conditions.

This type of device uses electricity to produce bubbles of oxygen.

Does a waterfall oxygenate water?

Waterfalls can be a great way to oxygenate water. This is because the falling water creates a vortex which pulls in air and water vapor.
