Quarantining new koi is an important step to protect your existing pond from potential diseases or parasites. When you bring home new fish, place them in a separate tank or pond for at least two to four weeks before introducing them to your main pond. This quarantine area should have proper filtration, aeration, and stable water conditions similar to your main pond.
Monitor the new koi closely for signs of illness, such as changes in behavior, appetite, or appearance. During this period, it's common to perform preventative treatments for parasites using products like salt or specific medications, but only under proper guidance. Regular water testing and partial water changes help maintain a healthy environment during the quarantine process. Avoid sharing equipment like nets or buckets between the quarantine and main pond to prevent cross-contamination. Once the koi appear healthy and show no signs of stress or disease, they can be safely introduced to your established pond.
