Keeping a jellyfish as a pet can be a rewarding and relaxing experience. Jellyfish are beautiful and intriguing, but caring for them can be tricky a little tricky if you don’t stick to the following habits. Here are some important tips for acclimating your jellyfish to their new home and maintaining the right water quality.
Floating the Bag
Float your new jellies in the bag they came in inside your tank allowing the temperature of the water inside the bag to match the temperature of the water in your tank. This can take between 15 and 20 minutes depending on the size and location of your tank. Rotate the bag every 2 to 3 minutes to stimulate the jellies helping them to retain their healthy bell-like shape. This also helps mix the water in the bag.
Measure the Temperature
Check the temperature of the bagged water, comparing it with the temperature of the tank water. Be sure the temperatures match before you go on to the next step.
Acclimatizing Water Chemistry
Once the temperature of the bag has matched the tank, you may begin to introduce small chemical changes within the bag. This process is called water chemistry acclimation.
Open the bag with the jellyfish and pour or scoop water out with a small plastic cup. Remove about 20% of the water in the bag. Then, very gently replace about 20% of the bag water with water from of your tank. Then, carefully secure the bag with a rubber band and once again, allow it to float in the tank. Leave a small amount of air in the bag as you tie it up so that it floats easily.
Continue rotating the bag to gently every 2 to 3 minutes to stimulate the jellies and help them to move the salt water through their bodies. They need to be active in order to move the water through their systems and acclimate properly, and they need your help them do that. Their natural environment is always in motion, and that motion supports their bodies. Therefore, you should very gently simulate that motion.
Perform 4 or 5 of this these 20% water transfers for an hour as you slowly help your jellies become comfortable in their new environment. This step is critical to your jellies health and survival, so do not rush. Complete the process within 1 to 2 hours from temperature acclimation to fully introducing them to your tank. While you must do this gently and slowly, your jellies should be out of their bag within two hours. Any longer than that endangers their health.
Release the Jellies into the Tank
Now that you’ve acclimated your jellies, they should be belling nicely in the bag. You may release them into your tank.
- Leave the bag in the water.
- Open the bag gently
- Allow the jellies to move out of the bag on their own
Enjoy the show!
