Green Star Polyps are not very sensitive to the intensity of lighting provided. You can keep them almost anyway in the tank, most of the time reefer like to glue GSP on overflow box, or back wall, and it will grow over and make gress like wall.

Moderate to high water movement is recommended for Green Star Polyps. These polyps require enough water flow to keep detritus from settling on them. Increased water flow also appears to speed up their growth rate.

Pachyclavularia relies heavily on the products of their zooxanthellae but also may feed on phytoplankton and similarly sized microfauna in the water column.
