Sinularia dura is a soft coral in the family Alcyoniidae that develops broad, folded lobes with a firm yet flexible leathery texture. Its colonies commonly display beige, brown, cream, or greenish coloration, while their layered, leaf-like structure creates a strong natural presence and gentle movement within reef aquariums. Sinularia dura relies largely on photosynthesis performed by symbiotic algae within its tissues, so maintaining stable water chemistry, moderate lighting, gentle to moderate water movement, and sufficient distance from neighboring corals is essential for supporting healthy expansion and long-term growth.
