These invertebrates, which are not corals - they have no skeleton - are known as discus anemones. They live attached by a foot that is less powerful than that of the anemone. The diameter of the discshaped polyp varies from one species to another. The presence of Zooxanthellae demands strong light. Asexual reproduction through budding is possible in captivity. Size: 10-30 cm. Actinodiscus
Several species from this genus are available on the market, and they are easy to keep. Their feeding, identical to that of the animals above, should take place on a weekly basis, as Zooxanthellae supply a part of the substances they need to live and they sometimes reject the food offered by the aquarist.
