The fish are packed with plenty of oxygen and water to get them through the night. They are kept in the secure caged part of the vans and are handled with care. When the fish arrive, carefully float the bags in the pond to acclimatise them. Generally, we recommend floating the bags for around 30 minutes. After this we then recommend introducing small amounts of pond water to the bag for a further 15 minutes, prior to introducing them to their new home.
