Xenia elongata aka 'Pulsing Polyp'
A reef aquarium classic! Pulsing Xenia elongata polyps enliven your reef with mesmerizing motion. A fast grower, so be sure to put it in an area where it won't out compete your other corals. Consider growing it on an 'island' in your sandbed, or on the back of the aquarium glass. The smaller colonies ship considerably better than adult colonies.
