Heteractis magnifica, also known by the common names magnificent sea anemone or Ritteri anemone, is a species of sea anemone found in the Indo-Pacific area; it can grow up to 1 m (3 ft) in diameter in the wild. It can be kept in aquaria, but is considered one of the most challenging species to keep healthy. H. magnifica consumes both vertebrates and invertebrates, including fish and crustaceans.

H. magnifica was featured in the Pixar Animations film Finding Nemo.

Classification[edit]

The anemone was formerly classified as Radianthus ritteri, but has been placed in the genus Heteractis, a group of tropical clownfish-hosting anemones.

Environment and Distribution[edit]

As well as providing shelter for anemonefish, H. magnifica may also host several shrimp species and the Porcelain Anemone Crab (Neopetrolisthes ohshimai). It forms a mutualistic relationship with the fish, providing protection with its nematocysts in exchange for nourishment from the fish.[1] It is also found in association with anemonefish, or clownfish, such as the cinnamon clownfish (Amphiprion melanopus), Clark's anemonefish (A. clarkii), common clownfish (A. ocellaris), black-finned anemonefish (A. nigripes), true clownfish (A. percula), pink skunk clownfish (A. perideraion), and Juvenile threespot dascyllus fish (Dascyllus trimaculatus).

The anemone is found in the Indo-Pacific and Red Sea, in reefs 33 to 3 feet below the surface. It generally lives in temperatures from approximately 72.0 to 82.0° F 90 (22.2 to 27.8° C).
