Creating ideal conditions for new aquarium arrivals

Why should you acclimate
your new arrivals?
Follow these simple steps to
acclimate your new arrivals:
- Never open the shipping box in a brightly lit area. Sudden bright light, after being in a dark box, can be stressful to your new fish. Turn the light off in your fish tank and float the bag in the tank for 15 minutes. This is to start adjusting the temperature.
- After 15 minutes, open the bag and place the fish, with the water it arrived in, into a clean bucket or container (Note: this means the bucket or container has never contained any soap or chemicals which may be harmful to your fish.)
- Add half a cup of water from the tank your new arrivals will be placed in into the bucket or container. Repeat this step every five minutes for 15 minutes.
- Next, discard half of the water from the bucket or container, and continue adding half a cup every five minutes for another 15 minutes.
- Carefully net the fish from the container and release them into their new home. Discard all of the acclimation water. DO NOT add it to your tank.
- After your new fish are introduced to your tank, leave the lights off for a few hours. Do not be alarmed if your new fish don’t start eating right away. Most fish will take a day or so to feel comfortable to eat.
