The tentacles of Clavulariidae resemble palm fronds hence the common names associated.  Clavulariidae form encrusting mats on the rocks or substrate.  With the variety of colors and textures found in the genus these corals make a beautiful addition to any reef aquarium.  Clavulariidae corals are very easy to care for and recommended for beginners.  They also help reduce organics in the water which can help improve water quality.
