The Haddon's Carpet Anemone, a vibrant and solitary creature, thrives in the shallow waters of the Indo Pacific and Red Sea. Typically found away from the reefs, it prefers soft muddy or sandy substrates and can grow up to an impressive 3 feet in diameter. Also known as Haddon’s Anemone, Saddle Anemone, Saddle Carpet Anemone, or Saddleback Anemone, it can be identified by its short, blunt tentacles that deliver a potent sting. Unlike its close relatives, Stichodactyla gigantea and Stichodactyla mertensii, this anemone lacks any coloration, spots, or markings on the underside and down its column.

In the wild, the Haddon's Carpet Anemone plays host to various Clownfish species, including Amphiprion clarkii, A. sebae, A. akindynos, A. chrysogaster, A. chrysopterus, and A. polymnus. In home aquariums, it can also accommodate Amphiprion ocellaris, A. percula, and A. allardi.

Providing proper care for the Haddon's Carpet Anemone requires a well-equipped tank with strong lighting and good water movement. The aquarium should offer a mix of sandy and rocky areas as this anemone tends to move around and seek preferred spots. It has a preference for burying its foot into the sandy bottom and sometimes attaches itself to the aquarium glass for protection, with its column fully submerged. When introducing it to the tank, it's advisable to prepare a specific sand bed location, reducing the flow rate temporarily to allow the anemone to settle and anchor itself. Afterward, the flow rate can be restored to its usual level.

Keep in mind that the Haddon's Carpet Anemone possesses a potent sting that may harm corals and other anemones in the aquarium. It's not compatible with other anemones within a 12" diameter, so close monitoring is necessary during its initial introduction. Additionally, it can potentially prey on fish other than clownfish, so caution should be exercised when housing it with other fish.

Handling a healthy Haddon's Carpet Anemone requires care as they are exceptionally sticky to the touch, making it challenging to detach them from objects without causing damage. Moreover, they can cause severe reactions in humans, emphasizing the need for cautious handling.

While relatively easier to care for compared to other "Carpet Anemones," this species still poses challenges and is best suited for experienced aquarists. Proper care involves maintaining a fully established aquarium with ideal water chemistry, adequate flow, and strong illumination. Regular feeding, possibly even daily, with suitable marine foods like fresh fish, uncooked shrimp, and other meaty options is essential for their well-being.
