Aurelia aurita are non-venomous jellyfish that may be cultivated in tanks that have freely circulating water and smooth surfaces. Also known as "moon" or "saucer" jellyfish, these creatures may live for up to a year in a tank on a diet of frozen plankton. Despite their appearance, these creatures are relatively easy to care for; jellies eat frozen plankton mixed with tank water 1 - 2/x daily; if fed more frequently, jellies will increase in size. Jellyfishart.com sells tanks, food and jellyfish; jellies are express-shipped in styrofoam containers and are guaranteed to arrive alive.
