The Longfin Fairy Wrasse (Cirrhilabrus rubriventralis) is a peaceful, reef-safe marine fish known for its vibrant coloration—especially in males. Native to the Red Sea, it thrives in a well-maintained 55+ gallon reef tank with moderate flow, stable parameters, and plenty of live rock for hiding. This wrasse does not burrow but may spin a mucous cocoon to sleep. A tight lid is essential, as they are expert jumpers. Feed a varied, protein-rich diet 2–3 times daily, and avoid housing with aggressive tankmates. Males can show dominance and enhanced colors, especially when courting or establishing hierarchy.
