__Basic__ The Green Star Polyp is a hardy coral which means it is easy to grow in fish tanks and makes it a good coral for people to start off with in there own salt water fish tank. The scientific name is Clavularia viridis, and its classification is a soft coral. Green Star polyps are small bright green polyps. Polyps being ... They are connected together by a rubbery purple colored mat. That opens during the day, retracted at night or when disturbed. __Lighting__ We found that "they will tolerate fairly low light levels, but tend to develop brighter colors under higher intensity lighting."- (http://www.reefcorner.com/SpecimenSheets/greenstars.htm). Now we are putting this to the test, and seeing if this is true and how it is different. __Experiment__We placed three parts all around the same size on a square piece of cement and clued the green star polyp to it. We then placed these three corals in different places in the tank. We placed one, facing right up towards the light, we placed the second one in the shadows, we placed the last one face down with no light.
