Common name: gigantic sea anemone

General information

The Giant Carpet Anemone, Stichodactyla gigantea, is a large and striking species of sea anemone that can be a centerpiece in any reef aquarium. It is known for its vibrant colors, which can range from green to blue, purple, or brown, and its expansive oral disc that can stretch up to 80 centimeters in diameter. This species is often sought after by advanced aquarists due to its size and the dramatic visual impact it creates.

Care

Caring for Stichodactyla gigantea requires a spacious tank with stable water conditions and strong lighting to mimic its natural shallow water habitat. It prefers sandy substrates where it can anchor its base. The Giant Carpet Anemone is a photosynthetic species, relying on symbiotic algae known as zooxanthellae for nutrition, but it also benefits from occasional feedings of meaty foods like fish, mussels, or shrimp.

Reproduction

In the wild, Stichodactyla gigantea reproduces both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction occurs through pedal laceration, where pieces of the base detach and develop into new anemones. In the aquarium, asexual reproduction is more commonly observed.

Symbiosis

Stichodactyla gigantea is well-known for its symbiotic relationship with clownfish, particularly the @species:amphiprion-clarkii (Clark's Clownfish) and @species:amphiprion-ocellaris (Ocellaris Clownfish). These fish find shelter among the anemone's tentacles, gaining protection from predators. The anemone benefits from the clownfish's waste as a nutrient source and the increased water circulation from their movement.

Habitat

The Giant Carpet Anemone is found in the Indo-Pacific region, from the Red Sea to Australia. It typically inhabits shallow lagoons and reef flats where it can receive ample sunlight. It is important for aquarists to replicate these conditions as closely as possible to ensure the health and longevity of the anemone in captivity.
