Spiny Sea Fan

About

The spiny sea fan (Muricea muricata) is a gorgonian coral native to the Western Atlantic, ranging from the Caribbean up through the coastal waters of the United States and Canada. In the wild it occupies very shallow reef zones, often just a meter or two down, where it regularly experiences strong water movement and good light penetration. The colony grows in a branching, tree-like form covered in small, spiny polyp calyces that give the coral its textured, rough appearance and its common name. Coloration tends toward browns, tans, and golds, which is typical for photosynthetic gorgonians that rely on zooxanthellae. In the aquarium, this species needs robust, consistent flow to keep its polyps healthy and prevent detritus from settling on the branches. This is probably the single most important factor in keeping it long-term. Lighting requirements are moderate, so it fits into a wide range of reef setups without needing to be placed directly under intense fixtures. It is considered reef safe and poses no threat to other corals or invertebrates. Intermediate care level is a fair assessment. Beginners who can nail down stable water quality and strong flow will have a reasonable shot, but it is less forgiving than many soft corals.
