Blue Blubber Jellyfish

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: Rhizostomeae
Family: Catostylidae
Genus: Catostylus
Species: C. mosaicus

Scientific name: Catostylus Mosaicus
Common names: Blue Jellyfish, Blue Blubber Jellyfish

Overview: Blue blubbers are also common species for jellyfish aquariums and relatively easy to keep. This species is distinguished by their dome shaped bell with eight oral arms which look like cauliflowers. They are popular by their variety of colours from light blue to dark purple and burgundy. There are sometimes white and brown colour ones, which are thought to depend on the species of symbiotic algae living inside their body. They are strong and active swimmers.

Harmful to humans: No

Maximum size: Bell diameter up to 35 cm (14 inches)

Colour: light blue to dark purple and burgundy. Sometimes creamy white/brown

Life span: a few months in captivity, up to 10 months in wild

Feeding: Small Plankton, Photosynthesis*

Photosynthetic: Yes*

Habitat: Coastal Waters

Distribution: Eastern Australia, Philippines

Temperature range:

Optimum aquarium temperature: 25 °C

Salinity range:

Optimum aquarium salinity: 34ppt to 35ppt

Optimum flow speed: Medium to strong

Other notes: *Even though they have symbiotic algae inside their body, the rate of photosynthesis contributing to their energy requirement is not great. Recently aquarists showed that they could be kept healthily by only feeding without full spectrum light. As they are strong swimmers, the top of their bells got easily damaged by hitting bottom and walls of the tank. Keep the bottom and walls of your tank as smooth/ clean as possible, and keep jellyfish away from bottom and walls by increasing flow speed.
