How many koi fish can I put in my pond?
A The amount could range from 150 to 250 gallons per fish. If you are starting out with small 6″ to 8″ long koi, they can reach 2 feet in three years, depending on how much food and how often you feed them. They could even grow to over 3 feet long! The overcrowding of fish produces stress and a lot of waste material. It can reduce the health of the fish and result in various diseases. Also, a less crowded pond is more pleasant to look at.
