Why are my koi inactive?
Change is stressful, even for koi fish. Water quality, pH levels, or oxygen levels changing can be the cause of your koi fish always hiding. This is especially true for the summer when water holds less dissolved oxygen. Without the right levels of dissolved oxygen, your fish can start having health problems.
How can I make my koi more active?
Being more active means more frequent feedings. So between higher water temperatures, undigested food, and waste increase, the water parameters (especially ammonia levels) can quickly become a problem. The standard recommendation is at least one 10-20% water change per week.
Why do koi jump at night?

Why are my koi fish hiding or at the pond bottom?
This can cause your koi fish to hide more often out of fear of becoming fish food. One of the best ways to protect your fish is by installing fish tunnels or caves.

What should I do if my koi fish is not eating?
Test it in the morning and evening to get an average pH level. You’ll want to use an aerator to oxygenate the water. This is especially true for the summer when water holds less dissolved oxygen. Without the right levels of dissolved oxygen, your fish can start having health problems.
What happens if a fish dies in cold water?
Similarly, a fish that prefers warm water will likely die in cold water. But just because your fish isn’t dead yet doesn’t mean that your setup is right. In fact, while your fish appears to be surviving, it may be stressed beyond belief. And as we discussed earlier, stress can lead to an early death.
Do koi fish go dormant?
Well, Koi fish actually go into a certain type of hibernation, called torpor, that allows the animal (or in this case, fish) to regulate their body temperature to acclimate to the air or water temperature. While in this state, even though it may seem like they are napping, they are really just slowed down.
How long can koi survive without pump?
How long can Koi survive without a pump? The fish can survive under these shallow-water conditions for more than two days, maybe even a week or more, unless they are really crowded or not in full health to start with.
