Green Star Polyp
Pachyclavularia sp.
This coral forms a basal encrustation from which numerous green polyps emerge. The polyps are retractable and open in light. It can quickly cover rocks and decorations. Its growth is moderate to fast depending on conditions. It is very hardy and tolerates a wide range of parameters. In aquariums, it can become invasive if not controlled. It lacks a calcareous skeleton.
