The Heteractis magnifica, commonly known as the Ritteri Anemone, is a large sea anemone that can reach over three feet in diameter in the wild, but typically grows to 1.5 feet in the aquarium. It was previously referred to as Radianthus ritteri, but the name has been changed. The anemone's tentacles are long and non-tapering, and may appear swollen at the tips. They can retract almost completely into the base.
To thrive, the Ritteri Anemone needs strong lighting and intermittent water movement within the tank. It usually prefers a high point in the tank to receive ample light, but may move around to find the best conditions. Its powerful sting can harm corals, so care must be taken when placing it in the aquarium. The presence of a clownfish, such as Amphiprion perideraion, can help it acclimate. Ritteri Anemones from different locations may serve as hosts to other clownfish and shrimp.
The Ritteri Anemone's diet should consist of mussel, fish, crustaceans, and frozen foods.
