FAQs

Your aquarium can be set up in a variety of locations. Most of our customers keep pet jellyfish at home, in the office or in a showroom.

Be sure to set up your jellyfish tank out of direct sunlight and near a power supply for the pumps and lights.

This depends on which aquarium you have. As a general rule, we recommend that you have one jellyfish for every 5 litres of water in the tank.

For example a 45 litre aquarium can house 9 jellyfish (45 divided by 5 = 9).

Jellyfish cannot live in a normal aquarium. They require aquariums that have no corners, a constant water flow and a protected outlet. Therefore jellyfish aquariums need to be made specifically for jellyfish. All our jellyfish tanks have been purpose built with jellyfish in mind.

Jellyfish can last up to three days without food. So if you were planning on a trip away this weekend your free to go!

Jellyfish feed continuously in the wild so we recommend you feed your jellyfish every day. The exact amount of food required to feed your jellyfish will depend on the type of food you have purchased. Each food order will come with a dosage information sheet.

In the wild jellyfish feed on all sorts of creatures. Some of their favourite food includes ZooPlankton, PhytoPlankton, Brine shrimp and even other jellyfish!

We feed our jellyfish live brine shrimp for the best source of nutrition…

Jellyfish are seasonal creatures. Their lifespan is up to 14 months.

Jellyfish grow into their surroundings. So depending on the size of your aquarium your jellyfish will grow in relation to the space around.

Moon jellyfish in an aquarium can grow up to 10 cm plus!

No. Some would say you can keep moon jellyfish with blubber jellies but it is best to keep the two species separated.

All of our jellyfish are Captive Bred in our jellyfish laboratory. Captive Breeding means all of our jellyfish are disease free and have a longer life expectancy than jellyfish fished from the sea!

Always check the origin of your jellyfish!

This is called inversion. Jellyfish are sensitive to water conditions, if the water is too hot or too cold the jellyfish will invert. To fix this bring the temperature back into their range, Lower temperature is best. Check the salinity and they should go back to normal.

Jellyfish are very delicate. Introduced to a ‘normal’ aquarium you jellyfish would be cut to pieces by filters, corners, heaters etc. We sell custom made jellyfish tanks purpose built for jellyfish.

All of our live jellyfish are shipped overnight. If you would like to specify a delivery date, please state this in the delivery notes box on the checkout page.

Our jellyfish are double bagged, packaged in a polystyrene insulated box and surrounded by packaging. Jellyfish won’t last forever in their bags so they are sent for next day delivery.

We recommend a 20% water change every week to keep your tank looking crystal clear.

First you will need your RO water. You can pick this up from any local aquatic stores.

Then you will need your salt. Any aquarium grade salt will be fine for moon jellyfish.

Your salinity (Salt level) should be 25 grams per litre of water.

So for example you have the Medusa 45 Premium Package. This aquarium is 45 Litres.

25 grams of salt x 45 (Litres) = 1125 (Grams)

You will need 1.125 KG of salt for 45 Litres of water.

Ammonia and nitrates can kill jellyfish so you need to keep them to a minimum. You can test your nitrates and ammonia using a simple marine test strip found in your local aquatics store.

Your ammonia and nitrates reading should read 0.

Ammonia and nitrates appear when you have been feeding your pet jellyfish too much or you haven’t cleaned the tank in a while.

If you need to get rid of ammonia or nitrate you need to do a partial water change every day until the levels drop back to zero.

To test salinity you can use a refractometer or hydrometer. These can be purchased at your local aquatic stores. These instruments give you a clear indication of how much salt is in your water.

Your water should be between 20-30ppt (Thats 20-30 grams of salt per litre).

You can test your water temperature using a digital thermometer found in your local aquatics store. Your water should be between 17-21 degrees celsius.
