We at The Fish Room would like to try and help you make the acclimatization process as easy as possible for you and your new pet. We have enclosed what we believe to be the best practice for introducing new fish into your aquarium.
If you have a quarantine aquarium available, we strongly encourage you to quarantine your new pet for 4 weeks before you introduce it into your main display aquarium. If you do not have one available, we encourage a very close monitoring system for the first 4 weeks, remember the faster you detect any issues (if you have any) the better chance you have to successfully treating the problem.
Step 1: If you know you have fish arriving, we suggest doing a water change and feeding your current aquarium within half an hour of the time you are introducing your new pet. This will lower the nitrate level and fill the bellies of your new fish and should lower the chance of aggression. If you are introducing Cichlids or predatory fish, we would encourage changing decorations as well so no territory has been established.
Step 2: Float your bag in your aquarium for 10 minutes. This will ensure the temperature from bag to aquarium match.
Step 3: Open the new bag and remove some of the water from the bag and replace it with the same amount from your aquarium.
Step 4: Add 1 cup of aquarium water to the bag. Repeat this process for every 15 minutes for 2 hours. This will ensure that the water chemistry does not shock your new pet.
Step 5: Catch your new fish from the bag and place into your new aquarium.
Do not add the bag water to your aquarium.
Step 6: We encourage you to leave your aquarium lights of for the rest of the day to help your new pet settle in.
