The Ritteri Anemone is also referred to as the Magnificent Anemone or Heteractis Magnificent Sea Anemone. Some aquarists still refer to it as Radianthus ritteri, but this name was recently changed to the current H. magnifica. It can grow to over three feet in diameter in the wild, although it generally does not grow larger than 1½ feet in the aquarium. Its tentacles have a long, non-tapering shape that may, on occasion, appear swollen at the tips. They can almost completely retract into the base.

This Anemone requires strong lighting combined with strong, but intermittent, water movement within the tank. It generally prefers a high point in the tank to ensure it obtains all the light it needs, but it may change locations, seeking the ideal conditions. Its strong sting can harm corals. The presence of a Clownfish, such as Amphiprion perideraion, will help it acclimate. Ritteri Anemones from different locations may serve as hosts to other clownfish, and even shrimp.

The diet should include mussel, fish, crustaceans, and frozen foods.
