Australian Spotted Jellyfish
Phyllorhiza punctata
A hardy and charismatic jellyfish that make a great option for the home aquarium. Natively found around Australia, but also found invasively in other parts of the world, including the Atlantic and Pacific coasts of America. Often confused with the similarly named Spotted Lagoon Jellyfish.
Caring for Australian Spotted Jellies
Color can vary from a deep blue to a golden brown color depending on how much light they are receiving. These jellies have a symbiotic relationship with an algae called zooxanthellae. The more algae present, the more golden brown the jellies will be.
​
Stocking density: ASJ don't have true tentacles, just feeding arms, so the risk of them tangling is quite slim. Because of this, you can keep several together in the same tank. They do grow fairly quickly and can get quite large if you let them, so you may stock at a low to medium density to allow your jellies to grow some.
​
Flow: Low- medium flow. Australian spotted jellies are fairly capable of swimming on their own and they don't like to be pushed around the tank. Too much flow can lead to funny looking "leggy" arms and misshapen bells. Provide just enough to flow to keep them swimming up off the bottom of the tank.
​
Feeding: Having hundreds of tiny mouths, instead of one central mouth, ASJ do best with small food items. Live baby brine shrimp are a great option. Some nutrition will also come their symbiotic algae, so it is important to provide them with adequate lighting.
​
Temperature: 77-82F we like to keep our tropical jellies on the warmer side, around 80. Keeping them below 77 will lead to slowed growth/metabolism and eventually mortality if below 74/72 F.

Salinity: 1.023-1.026 SG 31-35 PPT.
