If you disagree with any of the information shown, please comment in the thread below and we will edit accordingly.

Kingdom: Animalia
Phylum: Cnidaria
Class: Scyphozoa
Order: Rhizostomae
Family: Cassiopeidae
Genus: Cassiopea

Common Names: Upside Down Jellyfish
Scientific Name: Cassiopea sp.

Overview:Upside down jellyfish is so called because it spends most of its time on mudflats with its bell against the sea bed and its tentacles pointed towards the water surface. This jellyfish is one of the easiest species to keep as it does not require a kreisel system. They could be kept even in plastic bottles when they are small. The variation in their colour is one of their attractions, such as blue, green, orange and brown with usually white stripes on their bells. Even though they are photosynthetic, they still require to be fed baby brine shrimp regularly to grow healthily.

Harmful to Humans: The stings, appearing in the form of a red rash-like skin irritation, are notorious for being extraordinarily itchy.

Predators: water crabs

Maximum Size: Adult bell diameter between 20cm (8 inches) and 35cm (14 inches)

Colour: shades of white, blue, green and brown

Life Span: 5 years

Feeding: Small Plankton, Photosynthesis

Photosynthetic: Yes

Habitat: Shallow mangrove swamps, mudflats, and turtle grass flats

Distribution: Caribbean, Indo-Pacific, Gulf of Mexico

Temperature range: 23°C to 26°C

Optimum Temperature: 25°C

Salinity Range: 34ppt to 35ppt

Optimum Salinity: 34ppt to 35ppt

Other Notes: Upside down jellyfish could be kept in normal fish tank with sunlight. Avoid direct sunlight by making shades of curtain, and be careful for the increasing temperature (not over 28 C). They could look very similar to a sea anemone with very strong poison (Phyllodiscussemoni) in the ocean bed. Please do not touch them in the sea unless you are absolutely sure that they are upside down jellyfish.

Upside down jellyfish spend a lot of time on the bottom and as our tank is designed specifically to keep jelly's off the bottom it wouldn't suit this jellyfish. Our tank is designed for pelagic(free swimming) jellyfish where as Cassiopea spend a lot of their time on the bottom of the tank so they are considered a benthic species.

Upside down jellyfish are actually one of the easier jellyfish species to keep in a home aquarium, you can keep them in a system set up very similar to a reef aquarium with reduced water flow.

Cubic jellyfish tank makes gentle flow which would be good for upside down jellies too. But the LED does not support enough light for them to photosynthesize.
