Now, it is ready for the fishes to be added into your aquarium.
Do not simply open the plastic bag and put the fish in the tank together with the water in the bag. It may impose a shock on the fishes. Firstly, put the plastic bag containing the fish in the aquarium water and let it float unopened for about 15-30 minutes to allow the temperatures to adjust. Then, slowly add the aquarium water into the plastic bag to eliminate the difference in water quality. Now, it is ready for the fishes to be added into your aquarium.
