However, you have several ways of preventing that. For one, you can turn off your skimmer or filter or stop it from pumping during feeding time. Better yet, you can just float an O-ring and throw the food there. That way, it will stay in one place and avoid getting sucked.


Sinking types of koi fish food tend to suit the nature of your koi fishes since they are natural bottom feeders. As such, they’re more comfortable when eating at the bottom.

With this, they’ll eat more and get more nutrients compared to the floating. Hence, you’ll see better results in terms of weight and color.

However, since they’re just at the bottom, you can’t check observe them nor check on their conditions.
