Heliofungia actiniformis
Solitary LPS coral with long tentacles resembling anemones. Clownfish may host in it. Placed on sand — beautiful long tentacles swaying in current.
Heliofungia actiniformis (family Fungiidae) is a solitary, free-living coral from sandy bottoms and lagoons of the Indo-Pacific whose long, extended tentacles closely resemble a sea anemone. It rests unattached on the sand and continuously extends and waves long, thick, color-tipped tentacles, earning the name long-tentacle plate coral. Colors include greens, browns, pinks, and purples. Provide moderate lighting and gentle to moderate flow, and place it directly on the sand. It is delicate, easily damaged, and sensitive to shipping and handling stress, making it a somewhat challenging species. Its long tentacles can sting and harm nearby corals, so allow adequate spacing. Feeding once or twice weekly maintains health and coloration.
