Tank/Pond Size: Minimum 1,000 gallons for a small group, as they can grow up to 3 feet in length. Ponds should be at least 3 feet deep to provide adequate space and protection from predators.
Temperature: Maintain water temperature between 59-77°F (15-25°C). Koi can tolerate a wide range of temperatures but thrive best in this range.
Diet: Feed a varied diet of high-quality Koi pellets, supplemented with fresh vegetables and occasional treats like earthworms or shrimp. Feeding should be reduced during colder months when their metabolism slows.
Pond Setup: Provide a spacious, well-filtered pond with aeration to maintain high water quality. Include plants, rocks, and shaded areas for a natural environment and protection from the sun.
Water Quality: Maintain excellent water quality with regular water changes (10-20% weekly) and efficient filtration to keep ammonia, nitrite, and nitrate levels low. Test water parameters regularly to ensure stability.
