The Tranquil World of Jellyfish: A Guide to Setting Up and Maintaining Your Own Aquarium

Choosing Your Tank:

The first step in creating a jellyfish aquarium is choosing the right tank. It's important to note that not all aquariums are suited for jellyfish, as they require specific conditions to thrive. A cylindrical or bell-shaped tank is ideal, as it allows for plenty of water circulation and space for the jellyfish to move. A 20 to 30-gallon tank is a good size for beginners, as it provides enough space while still being easy to manage.

Setting Up Your Aquarium:

Once you have your tank, it's time to set it up for jellyfish. You'll need a filter system that allows for gentle water flow, as well as a heater to maintain a consistent water temperature of around 78°F. It's also essential to use the right type of saltwater, as jellyfish require specific salinity levels. Aquarium supply stores typically sell pre-made saltwater mixes that are perfect for jellyfish tanks.

Choosing Your Jellyfish:

Not all jellyfish are created equal when it comes to keeping them in captivity. Species that are better suited to aquarium life include Moon Jellyfish, Blue Blubber Jellyfish, and Crown Jellyfish. It's important to research each species thoroughly before making a purchase, as their needs and behaviors can vary widely. Younger jellyfish, known as "polyps," are the easiest to acclimate to a new environment, making them a good choice for beginners.

Maintaining Your Aquarium:

After you've set up your aquarium and introduced your jellyfish, it's essential to maintain the proper conditions to keep them healthy. Regular water changes, typically once a week, are necessary to remove any accumulated debris or waste. It's also important to monitor the water temperature, salinity levels, and pH balance regularly. Jellyfish feed on small planktonic organisms, which must be added to the tank daily.


Creating an aquarium for jellyfish may seem intimidating at first, but with the right information and preparation, it can be a rewarding and peaceful addition to any space. By choosing the right tank, setting up the proper conditions, and selecting compatible jellyfish species, anyone can enjoy the tranquil world of these mesmerizing creatures.
