Sea Finger

About

Sea Finger (Alcyonium acaule) is a soft coral native to the Atlantic and Mediterranean, where it grows as a sessile colony anchored to hard substrate in subtropical waters. The name gives away its most recognizable feature: fleshy, finger-like lobes that extend upward from a common base, giving colonies a distinctive hand-like silhouette. Unlike many of the Indo-Pacific soft corals that dominate the hobby, this species brings a distinctly European character to a reef tank, which makes it an interesting choice for anyone looking to set up a biotope-style display representing Mediterranean or eastern Atlantic communities. It is listed as reef safe and rated beginner-friendly, which suggests it tolerates a reasonable range of conditions without demanding the obsessive fine-tuning that some other corals require. Moderate lighting and moderate flow appear to suit it well, keeping the polyps extended and the colony healthy without stressing it. Because detailed hobbyist keeping records for this species are relatively sparse compared to more commonly traded corals, it is worth seeking out others who have kept it and approaching its care with attentive observation rather than assuming it behaves exactly like better-documented Alcyonium relatives.
