20 minutes is all it takes to safely acclimate fish to your aquarium.
Time Required: 20 minutes
- Test the pH, and chlorine levels before adding fish to a new tank. Chlorine must be zero, and pH close to that of the pet shop. Verify that the water temperature is at the proper level.
- Turn the light off in the aquarium to reduce stress.
- Lift the lid and place the sealed bag containing the fish in the water so it floats.
- Let the bag float for ten minutes, then open the top of the bag.
- Using the measuring cup, place one cup of tank water into the bag.
- Close the bag and allow it to float for another five minutes.
- Repeat steps five and six once. For sensitive fish such as neon tetras repeat two or three times.
- Place the small net into the bag, lift the fish out, and quickly transfer it to the aquarium.
- Discard the bag of water in the sink (never in the aquarium).
- Leave the light off for several hours to allow the fish to adjust to the new setting.
- If you only have a large net, hold the net over a bucket and gently pour the contents of the bag into it. Then quickly transfer the fish from the net to the tank.
- If there are already other fish in your aquarium place the new fish in a separate aquarium for several days and observe for disease.
- Brine shrimp nets are an excellent choice to transfer fish with.
