The Moon Jellyfish, Aurelia aurita, has a saucer shaped body with long tentacles hanging down with a translucent body. They are best kept in tanks with vibrant neon or colored lighting to "illuminate" the jellyfish. Unlike other jellies, the Moon Jelly's venom does not affect humans whatsoever. They will eat live or frozen meaty foods and are best kept with members of their own species. They are not recommended for reef tanks and are best kept in tanks at room temperature.
