Giant Cup Mushroom Coral
The Giant Cup Mushroom Coral is also known as the Giant Disc Anemone, Giant Mushroom Anemone, or Giant Flower Coral, and sometimes the Large Elephant Ear. A member of the order Corallimorpharia (Stephenson, 1937), it shares some similarities to stony corals, which is why it is also known as the Giant Coral Anemone.

It is very easy to maintain in the reef aquarium with a medium light level combined with a low to medium water movement. It can expand to over 12 inches in diameter during the day. It is considered semi-aggressive and requires adequate space between itself and other corals. When a fish brushes against it, it forms a ball around the fish, from which the fish generally cannot escape. Since it eats fish, it is best kept in its own aquarium that has a sandy bottom and large rocks.
If kept in a reef aquarium, it should be fed large meals of Artemia and other plankton-like foods. It also receives some of its nutritional requirements from the symbiotic algae zooxanthellae hosted within its body.
