Family

Common name: Moon Jellies

Scientific name: Ulmaridae

Ulmaridae is a family of jellyfish known for species like the common moon jelly, Aurelia aurita. These jellyfish are characterized by their translucent, saucer-shaped bells and short, fine tentacles. They are popular in public aquariums due to their graceful movement and relatively simple care requirements. In home aquariums, they require specialized kreisel tanks to simulate open water conditions and prevent injury. Their diet consists mainly of zooplankton. While not common in the average reef tank, they offer a unique challenge for advanced hobbyists.
