Broad Sea Fan

About

The broad sea fan (Eunicella verrucosa) is a gorgonian coral native to the Atlantic Ocean and Mediterranean Sea, where it forms slow-growing, tree-like colonies on rocky reefs and walls in relatively cool, clear waters. Unlike the tropical gorgonians that dominate most reef tanks, this is a temperate species, which immediately sets it apart from the majority of corals available in the hobby. Its branching structure fans out in a single plane, creating that classic sea fan silhouette, and colonies can range from pale cream to soft pink depending on the individual and its polyp coloration. In the wild it is sessile, anchoring firmly to hard substrate and relying on passing water currents to deliver food to its tiny polyps. Because it comes from cooler, nutrient-rich Atlantic waters rather than the oligotrophic tropics, keeping it successfully means thinking carefully about the type of system you are running. A standard warm tropical reef tank is not the right home for this animal. It is listed as a beginner-level coral in terms of flow and lighting demands, but the temperate origin is the real consideration here. Anyone drawn to cold-water or species-specific display tanks will find this an genuinely interesting and distinctive centerpiece.
