Aquarium Requirements for Jellyfish

The type of aquarium you need for jellyfish depends on the species you want to keep. Here are some general guidelines:

Tank size: Jellyfish require ample space to swim and grow. A general rule of thumb is to provide at least one gallon of water per inch of jellyfish diameter.
Tank shape: Tall and cylindrical tanks are ideal for jellyfish because they provide ample swimming space and minimal water flow disruption. Avoid using tanks with sharp corners or edges, as jellyfish can become trapped and injured.
Pseudo-kreisel Tank: A pseudo-kreisel is specifically designed to house delicate marine life such as jellyfish. It is inspired by the kreisel design, which is a cylindrical tank that creates a gentle, laminar flow of water, mimicking the natural ocean currents. The pseudo-kreisel design ensures that the inhabitants are not harmed by sharp corners or strong currents. It also prevents the creatures from getting stuck in corners or being sucked into the filtration system. These tanks are often used in public aquariums and research laboratories. They are also popular among businesses that specialize in creating habitats for jellyfish.
Kreisel Tank: A kreisel tank is a type of aquarium that is shaped like a horizontal cylinder and is particularly suited for delicate aquatic animals such as jellyfish. The cylindrical shape facilitates a rotating, laminar water flow that simulates the natural habitats. Its gentle, non-turbulent water movement keeps planktonic organisms afloat and also aids in separating waste materials to prevent the inhabitants from being sucked into the filtration system.
Lighting: Jellyfish are sensitive to bright light and prefer dimly lit environments. You can use blue or red LED lights to provide a gentle glow and enhance the jellyfish's natural colors.
Filtration: A high-quality filtration system is essential to maintain stable water conditions and remove waste and debris. You can use a combination of mechanical, chemical, and biological filtration to keep the water clean.
Water flow: Jellyfish require a gentle water flow to keep them suspended and distribute food and oxygen. You can use a specialized jellyfish tank with built-in water flow systems or add a separate water pump to create a gentle current.
Water parameters: Jellyfish require specific water parameters, including temperature, salinity, and pH. Research the species you want to keep to ensure you can provide the appropriate conditions.

General Water Parameters:

* Tank Size: 3 liters per 1 inch jellyfish

* Salinity between 25-32ppt / 1.019-1.024sg

* Temperatures between 64-75F

* pH: 7.5 to 8.5

* Nitrite Ammonia: <0.1ppm

* Nitrate: <20.0ppm

* Phosphate: <2.0ppm

Jellyfish Propagation in Aquariums

Jellyfish propagation in an aquarium can be a challenging. Here are some general tips and considerations:

Choose the right jellyfish species: Different jellyfish species have different requirements for water temperature, salinity, pH levels, and feeding. Research the species you want to propagate to ensure you can provide the appropriate water conditions for their growth and reproduction.
Maintain stable water conditions: Jellyfish are sensitive to changes in water conditions, so it's essential to maintain stable water parameters. Use a high-quality filtration system, perform regular water changes, and monitor water quality regularly.
Provide adequate food: Jellyfish feed on plankton and other small organisms, so it's crucial to provide them with a steady supply of food. You can use commercially available jellyfish food or cultivate your own live food, such as brine shrimp or copepods.
Mimic natural conditions: In the wild, jellyfish larvae attach themselves to surfaces and grow into polyps before developing into mature jellyfish. You can mimic this process by providing surfaces for the larvae to attach themselves to, such as plastic or ceramic plates, and maintaining a gentle water flow to help distribute food and oxygen.
Separate mature jellyfish: Once your jellyfish have matured, it's essential to separate them to prevent overcrowding and aggression. You can use individual tanks or compartments within a larger tank.
Monitor jellyfish health: Keep a close eye on your jellyfish's health and behavior, as they can be indicators of water quality issues or disease. Look out for signs of stress, such as decreased swimming activity or a loss of tentacles.

Is it Legal to own Jellyfish?

The legality of owning jellyfish varies by country and state/province, so it's important to check the regulations in your area before purchasing jellyfish. In some places, jellyfish are considered exotic pets and may require special permits or licenses to own.

Below are a few US States Restrictions:

The ownership of jellyfish in Florida is unrestricted.

In California, a permit is required to possess and sell certain species of jellyfish. The California Department of Fish and Wildlife (CDFW) is responsible for issuing permits for the possession and sale for these species:

- Pelagia noctiluca (mauve stinger)

- Chrysaora achlyos (black sea nettle)

- Chrysaora colorata (purple-striped)

- Chrysaora fuscescens (Pacific sea nettle)

- Chrysaora melanaster (northern sea nettle)

If you want to possess or sell any of these species of jellyfish in California, you will need to obtain a permit from the CDFW. The permit application process includes providing information about the jellyfish you intend to possess or sell, as well as information about your facilities and qualifications for keeping jellyfish. It's important to note that possessing or selling these species of jellyfish without a permit can result in fines and other penalties. If you are interested in owning jellyfish in California, it's important to research the regulations and permit requirements carefully to ensure that you are complying with the law.

In Washington state, it is legal to own jellyfish, but there are some restrictions and regulations that you should be aware of. According to the Washington Department of Fish and Wildlife (WDFW), jellyfish are classified as "aquatic animals" and are subject to the same regulations as other aquatic animals in the state. This means that if you want to collect or harvest jellyfish from the wild, you will need a valid aquatic animal collection permit from the WDFW.

In the United Kingdom, it is legal to own most species of jellyfish, but there may be restrictions on the import or sale of certain species.

The Oregon Department of Fish and Wildlife (ODFW) does not require any permits or licenses for the ownership or possession of jellyfish, as long as they are not caught or collected from the wild. However, if you plan to collect jellyfish from the wild, you may need a permit from the ODFW, depending on the location and method of collection.

FYI

Before purchasing jellyfish, it's important to research the regulations in your area and ensure that you have the appropriate permits and aquarium setup to care for them properly.

It's also important to only purchase jellyfish from reputable sources that are ethically and legally sourcing their jellyfish.
