Care
Caring for Haddon's Carpet Anemone requires a well-established aquarium with stable water parameters. They need a sandy substrate to anchor their foot and ample space to expand without touching other corals or anemones, as they can be aggressive towards neighbors. Strong lighting and moderate to strong water flow mimic their natural reef environment, promoting health and growth. Feeding should consist of meaty foods like fish, shrimp, and other seafood.
Reproduction
In the wild, Stichodactyla haddoni reproduces both sexually and asexually. In aquariums, they can occasionally reproduce asexually through pedal laceration, where pieces of the foot develop into new individuals. Sexual reproduction is rare in captivity.
Symbiosis
Haddon's Carpet Anemone is well-known for its symbiotic relationship with clownfish, particularly the @species:amphiprion-clarkii and @species:amphiprion-ocellaris, which can live within the anemone's tentacles for protection. The anemone benefits from the clownfish's waste as a nutrient source and the clownfish is protected from predators.
Habitat
Stichodactyla haddoni is found in the Indo-Pacific region, from the Red Sea to Fiji, and from Japan to Australia. They typically inhabit shallow waters on sandy bottoms or reef flats where they can receive plenty of sunlight.
