Delicate Spiny Sea Fan

About

The delicate spiny sea fan (Muricea laxa) is a gorgonian coral native to the Western Atlantic, with its range taking in Bermuda and the coastal waters off Rio de Janeiro, Brazil. In the wild it grows on reef structures exposed to persistent water movement, forming loosely branched colonies armed with small but noticeable spines along the branches. Hence the common name. The overall appearance is delicate compared to many other muriceid sea fans, with a more open, airy colony structure that shows off its polyps well when they're extended and feeding. Like most gorgonians from this region, it relies heavily on filter feeding rather than zooxanthellae, which means flow is really the critical care factor in the aquarium. High, consistent water movement keeps the polyps actively sweeping particles from the water column and prevents detritus from settling on the branches, which can quickly lead to tissue recession. Moderate lighting is sufficient. This isn't a coral chasing photons. It's considered reef safe and won't bother its neighbors. Intermediate-level keepers who understand the flow and feeding demands of non-photosynthetic or low-light gorgonians will have the best success here. Regular target feeding with fine particulate foods will go a long way toward keeping a colony healthy long-term.
