A koi pond is a water feature designed to house koi, a type of ornamental fish known for their vibrant colors and patterns. These ponds can vary in size and shape, often featuring plants, rocks, and other decorations to create a natural environment. Koi ponds are typically constructed with a filtration system to maintain clean water and support the health of the fish. In addition to being visually appealing, koi ponds can serve as a peaceful retreat for relaxation and meditation. They are often found in gardens or backyards, providing a habitat for not only koi but also other aquatic life, such as frogs and turtles.
