Chameleon Sea Fan

About

The Chameleon Sea Fan (Paramuricea clavata) is one of the more recognizable gorgonians from the Mediterranean and Northeast Atlantic, where it forms broad, branching fans on rocky walls and slopes at depths typically ranging from around 20 to 40 meters. Its common name comes from the remarkable color variation seen across colonies. Some individuals display rich yellows or oranges, while others lean toward purples and dark reds, and the range in between is wide enough that two colonies side by side can look like entirely different animals. In the wild it's a filter feeder, relying on water movement to deliver the tiny planktonic particles it catches with its polyps. In the aquarium this translates to a need for consistent, moderate flow across its branches. Stagnant water is the enemy. Although it's listed as a beginner-friendly coral, that label comes with a caveat: gorgonians as a group reward attentive husbandry. Keeping the skeleton free of algae overgrowth and providing a nutrient-rich water column will go a long way toward keeping colonies healthy long-term. Given its Mediterranean origins, it appreciates slightly cooler conditions than the typical tropical reef tank, which is worth factoring in before adding one to an existing setup.
