Cassiopeia ephyrae  through to adult stage should be held at 24-26 Deg C. and a salinity of 30-36ppt. They have also been kept in brackish water too

The jellyfish contain symbiotic zooxanthellae giving them their brown colour so require a suitable  full spectrum light placed directly above the tank. A mix of daylight bulbs with a 5,000-6,500 K range and at least one within the blue range of 10,000-20,000 K will keep the zooxanthellae healthy and will give an attractive look to your tank. Lighting should be provided for 8-12 hours.

As they are a ground dwelling jellyfish Cassiopeia should never be kept in a kreisel. Any square, rectangular or cylindrical tank is good for them. Ensure the flow is not on too high as this can disturb them and can also deprive them of food. Live newly hatched artemia shrimp, enriched baby brine shrimp, rotifers or copepods can be used and should be fed twice daily, but a dosing system could be set-up to provide smaller but more regular feeds which would maximise growth. An airline or pump set to a low flow will move the live feed around the tank as naturally it will stay at the surface where the light is greatest.

The tank will require regular cleaning, hydroids and algae growth are increased in Cassiopeia tanks due to high lighting levels and overgrowth of these can cause the jellyfish's bell to shrink. Tank surfaces, airline, heater and gauze should be wiped using a sponge and siphon the tank when required. Substrate can be used so this will require regular gravel siphoning. If the tank gets too dirty then remove all the jellyfish into a suitable sized bucket and carry out a 100% W/C thoroughly cleaning the tank as the level goes down. Cassiopeia are one of the only jellyfish that you can move using a net so you can carry out a full tank clean fairly quickly.

When disturbed they can release mucous strands containing nematocysts that can cause a nasty sting so care must be given whilst handling or carrying out maintenance on this tank.  Gloves must be worn and you should never mouth siphon. Vinegar should be used on jellyfish stings, and any persistent or sever swellings or pain you should seek medical advice. 

Cassiopeia have been kept with a wide variety of fish and invertebrate species. Please contact us for a list and any further advice
