Blue Cannonball Jellyfish

Stomolophus sp. - Captive Bred

aproximately 1/2-1” diameter 

*We currently have a very limited number of these available!*

Blue Cannonball jellyfish were essentially a myth until fairly recently. Found in waters around Baja California, Mexico, these gorgeous deep blue jellyfish were difficult to access. Public aquariums in Europe finally started to captive breed them. Jellyfish Warehouse is happy to offer yet another new species to the US! 

Blue Cannonball jellies are an active species, resembling Blue Blubber jellies both in color and behavior. We rank them as a “moderate” care level species simply because they require live baby brine shrimp, and they like to eat a lot. Frequent, smaller meals are ideal for them. Otherwise, they are an easy and straightforward species with no special requirements. Starting out a sky blue color, they will darken to a deep ocean blue as they age and grow. 

At the Jellyfish Warehouse, we breed a specific strain or possibly a separate species that develops dark blue freckles across their bell.
