Common name: Soft corals

Alcyonacea, commonly known as soft corals, encompasses a diverse group of octocorallian cnidarians that are important components of reef ecosystems. Unlike their hard coral relatives, they lack a rigid calcium carbonate skeleton, instead possessing a flexible structure often reinforced by small skeletal elements called sclerites. This order includes popular aquarium species like leather corals, sea fans, and gorgonians, which are appreciated for their varied forms and colors. They typically require moderate lighting and water flow, and many harbor symbiotic algae called zooxanthellae, which can provide them with nutrients through photosynthesis.
