Accurately described as an encrusting coral, Green Star Polyps rapidly grow over adjacent rock work, coral, or even the glass of an established reef aquarium. They are a peaceful coral armed with the defensive capability of being able to retract or deflate each of their polyps in response to predation. They will not harm other corals that are placed close to their colony, but are susceptible to being damaged by any aggressive corals in the reef aquarium. They are easy to maintain in the reef aquarium and make an excellent candidate for the beginning through expert reef aquarist. They require a medium to high light level combined with a medium to strong water movement within the aquarium. For continued good health, they will also require the addition of iodine and other trace elements to the water.
The symbiotic algae zooxanthellae hosted within their bodies provide the majority of their nutritional requirements through photosynthesis. They also benefit from weekly feedings of micro-plankton or foods designed for filter feeding invertebrates.
