    Adding Fish to Your Pond: Safe Method

    If the pond fish are purchased locally, you can help acclimate the fish after floating by opening the bag and adding approximately 20% pond water by volume.

    We also recommend adding a detoxifier to the water contained in the bag as well as to the pond itself. Pond Detoxifier will neutralize any ammonia produced by the fish during transport, regenerate damage to the mucous membrane caused by netting, and reduce stress during acclimatization.

    Be careful not to leave the fish in the open bag for too long as available oxygen will quickly be consumed! If you have an air pump you can also drop a small air stone into the open bag to ensure proper oxygenation.

    After approximately 30 minutes, your fish are ready to be introduced to their new home. Scoop the fish out of the bag using a soft mesh net and release them into your pond. Discard the remaining water.

    NEVER dump the fish from the bag into the water without acclimating. This will cause extreme stress and can even cause death if the difference in water temperature and chemistry is extreme.

    Don't be alarmed if the fish head for the bottom of the pond, as this is quite normal. They will likely stay there until they become familiar with their new surroundings. New fish may also hide for a few days if there are caves as this helps them to feel less vulnerable while they adjust to the new fish and environment around them.

    Remember to always start small with a few fish and build the population slowly and steadily, and you’ll have a thriving pond full of fish in no time!

    Frequently Asked Questions

    A general guideline is 1 inch of fish per 10 gallons of water. A typical 11'x16' pond can comfortably support 8-12 adult koi with proper filtration.

    Koi eat specially formulated koi pellets. Feed once daily in warm months, use wheat germ-based food in spring and fall, and stop feeding when water temperatures drop below 50°F.
