Green star polyps are aggressive behavior is what gets it it’s food. They will grab and eat anything that is in length of the tentacles. They do not sting the neighboring corals. Their encrusting mat can quickly overtake other corals in a fight for space. Excellent beginner corals with stable water temperatures. The calcium levels must be up to living standards. This coral appreciates the addition of iodine. The Green Star Polyp needs mild to severe amounts of light. They also need a good amount of water flow. They get their food in the nutrients from symbiotic algae in their polyps


 * Classification**- Pachyclavularia spp.
 * Coral Type :** Soft Corals
 * Common Name:** Green Star Polyps
 * Alt Common Name:** Star Polyps, Purple Star Polyps, White Star Polyps, Grass Coral, Daisy Polyps
 * Distribution:** Indo Pacific, Phillipines
 * Lighting Requirements :** Low to high - this coral tolerates many types of lighting including normal output flourescent, power compact, VHO, T5 or metal halide.
 * Aggression:** High. Although the coral does not have a stinging capability, it's encrusting growth pattern can lead to rapid encroachment on its neighbors. Mat can be pruned with scissors if it starts to get out of hand. This is one of those corals that some hobbyist regret ever putting in their tank.
 * Hardiness:** This coral is quite hardy and great for beginners. It does better with higher water flow.
 * Growth Pattern :** Proficient growing - spreads out across live rock or substrate in a tentacle like manner.
 * Nutrition:** This species thrives primarily on Zooxanthellate and light.
 * supplements Required:** None required.

The green star polyp, or Clavularia viridis, are considered a soft coral. Green Star Polyp are open during the day and are retracted at night or when disturbed. Considered fairly fast growing and easy to care for, they are a favorite amongst beginner coral enthusiasts for their tanks. Green Star Polyp often attach themselves to the glass of aquariums, often creating a beautiful green backdrop.

The Green Star Polyp have distinctive eight-leaved tentacles on each polyp. They are colonial animals with several individual polyps attached to a piece of live rock. Their stems are usually quite short (less than 12mm). The base is a fused, encrusting mass which is rather rubber-like in quality and usually purple in color. Green Star Polyp have long been confused with Xenia, to which it superficially resembles.
 * Appearance**

Reproduction of the Green Star Polyp
The most common method of green star polyp reproduction in the marine aquarium is accomplished by division. This occurs as the basal mass increases in size and develops new polyps. They also reproduce with sperm and eggs being shed into the open ocean and found in colonies in far away locations, but this star polyp method of reproduction seems to be uncommon in a tank environment.

**Aquarium Conditions for Green Star Polyp**
All types of star polyps thrive in medium water flow. While considered very peaceful by nature, they can be aggressive in terms of rapid growth. This means that they should not be placed next to more aggressive corals that may harm them. Green star polyp do not have a stinging capability, although its encrusting growth pattern can lead to rapid encroachment on its neighbors.

**Feeding of Green Star Polyp**
Green Star Polyp contain a symbiotic algae, zooxanthellae, hosted within their bodies to provide for the majority of their nutritional requirements through photosynthesis. They also benefit from weekly feedings of micro plankton or foods specifically designed for filter feeding invertebrates.

**Health Threats of the Green Star Polyp**
The Green Star Polyp are highly resistant to disease but do occasionally suffer predation from certain snails and nudibranchs such as Pleuroleura. These polyps will not tolerate deteriorating water conditions, overfeeding or overstocking of fish. Occasionally, polyps refuse to appear from the basal structure that has been dormant for some months. Usually they can fully recover if proper tank conditions are achieved.


 * Conclution

The project we did is on green star polyps. It started by us putting our coral on slabs of cement. Next we put the corals in a couple hundred gallons of water. Over many weeks we took info on the corals and used them to make a decition as a class wheather corals in light effects the corals grough better in dark cold water.**
