General Description
The Upside Down Jellyfish, scientifically known as Cassiopea sp., is a unique jellyfish species characterized by its flattened bell that rests on the bottom of the aquatic environment. This creature extends its frilly tentacles upwards into the water column to capture planktonic food and harness light, which is utilized by the photosynthetic algae residing within its body.
Aquarium Suitability (Expert Only)
This jellyfish is suitable for expert aquarists only due to its specific care requirements and sensitivity to environmental changes.
Demands and Care
The Upside Down Jellyfish demands a wide sandy bottom within the aquarium and necessitates high-intensity lighting for photosynthesis to take place effectively. It is intolerant of copper or high nitrate levels in the water, and abrupt fluctuations in salinity or pH can have severe consequences due to the jellyfish's high water composition.
Reef Suitability
Reef compatibility for this species is rated as 'No,' making it unsuitable for reef tanks due to its unique habitat and specific needs.
Aquarium Setup
When setting up an aquarium for the Upside Down Jellyfish, it is important to provide a minimum tank size of 113 liters with moderate to high lighting levels and medium water flow. The water conditions should be maintained with a pH range of 8.1-8.4, a specific gravity of 1.023-1.025, and a carbonate hardness (KH) of 8-12.
Behaviour
This species is generally peaceful, but care should be taken when handling it or performing maintenance within the aquarium due to its mildly toxic sting, although human response to the sting is rare.
Feeding and Diet
The Upside Down Jellyfish is a carnivorous creature that also acts as a filter feeder. It requires daily supplementation with zooplankton substitutes to meet its nutritional needs adequately.
