Green Star Polyps (Briareum sp.)
The Zoanthus Colony Polyp Corals are also referred to as Sea Mats, or Button Polyps. They are colonial animals with multiple individual polyps attached to a piece of live rock. The individual polyps of this variety are very small when mature, and offer a variety of texture for the reef aquarium. They are brown with shades of pink tones, and will brighten or darken depending on the lighting in the aquarium.
This is one of the best coral choices for the entry level reef aquarist. Incredibly tough and forgiving, the Green Star Polyp coral can tolerate a wide range of conditions. It grows by encrusting a purple mat over rocks and substrates and from this blossom a dense mass of electric green polyps.
