Long Polyp Neon GSP

Pachyclavularia violacea, or more commonly called Green Star Polyps, is a hardy species that is known to propagate with relative ease in adequate conditions. The stolon at the bottom of the GSP, often called the "purple mat" among aquarium hobbyists, is usually reddish to purple in color. The eight, smooth tentacles that emerge from each polyp can range in variation from yellow to green and surround the mouth of the polyp. Other color morphs do exist, but are not as common.
