[edit] Overview

In this curious, fascinating creature, the oral tentacles have large lateral appendages. These jellies have an alternation of generations, with a hydroidlike polyp as one stage, a swimming medusa the other. If polyps become established, they reproduce asexually and become a nuisance.

Family: Cassiopeidae

Other common name(s):

Native range:

Maximum height: 30 cm (12 in)

Minimum aquarium size: 380 L (100 gal)

Lighting: Bright illumination is necessary.

Placement: In full bright light.

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

[edit] Feeding

Zooxanthellate; can subsist for long periods without feeding if dissolved nutrient level is high. Feeds on small planktonic animals, like Artemia or Mysis, or feeder fishes such as mollies.

[edit] Aquarium Compatibility

Not suitable for the standard reef tank. Can sting and kill other animals. Has nematocysts and may be toxic to humans.

[edit] Notes

Requires water with little motion and will do best in a lagoon-type biotope or species tank. Outflow apertures and overflow boxes must be well screened. A well-established, productive sand bed is important as a source of live food.
