Koi fish can live with other peaceful fish that won’t compete for food, such as goldfish and minnows. Koi fish are a popular and beautiful addition to any water tank.
While they can live in a tank with other fish, it’s crucial to choose their tank mates carefully. Koi fish are active and require ample space to swim, so the tank should be big enough to accommodate them and their companions.
Since koi are large fish, they require peers that can tolerate their playful nature without becoming aggressive or territorial. Goldfish are the most common tank mates for koi, but other peaceful fish like minnows can work as well. Some species of catfish can also coexist peacefully with koi. However, fish like aggressive cichlids should not be housed with koi, as they can attack and injure them.
