The term KOI HABITAT refers to the environment in which koi fish live. A common habitat for koi is a POND, which is a body of water that is usually smaller than a lake and is often artificially created. Ponds are typically shallow and have a variety of aquatic plants and animals living in them. Koi ponds are designed specifically to provide a safe and healthy environment for koi fish, and they are often stocked with other species of fish, amphibians, and invertebrates.
