Can koi be put in a pond with a strong waterfall?

Yes, koi can be kept in a pond with a strong waterfall, as long as the pond is deep enough for them to escape strong currents and the waterfall is not too forceful. Koi are generally adaptable and can thrive in flowing water, which helps to keep the pond oxygenated. However, ensure that there are calm areas for resting and that the waterfall does not create excessive splashing or turbulence that could stress the fish. Regular monitoring of water quality is also essential in such environments.
