With the waving polyps flowing in the current, the Green Star Polyp adds color and beauty to the aquarium. The polyps of the Green Star Polyp can react quickly by not opening if there is any change in water parameters and, thus acting as good indicators of water quality, and flow. Therefore, it is a vital step to balance the pH, and alkinity accordingly to encourage growth and color of this beautiful coral. The Green Star Polyp is very easy to maintain and care, thus making it a very good choice for a novice aquarists. Care should be taken while placing this coral, because if it is placed in a proper region, it will grow quickly. A distance of six inches should be left between the Green Star Polyp corals for its proper growth. Though the Green Star Polyp is photosynthetic and receives nutrition using light energy, it also benefits from occasional bit of raw table shrimp or frozen Mysis shrimp. Use a turkey baster fortarget feeding. The Green Star Polyp is very hardy and does extremely well in most reef tank conditions. It thrives well in a temperature range of 74-84 degree Fahrenheit. Although, the Green Star Polyp does not possess any stinging cells or behavior, it shows high aggressive behavior due to its encrusting growth pattern that leads to rapid encroachment on its neighbor. It happens when a rock is crowded, the Green Star Polyp colony sloughs a waxy purple growth that glues another rock, and after few weeks it makes its own colony. The Green Star Polyp can propagate very easily by cutting that purple mat growth using a scissor and then can be get attached to a suitable substrate which will usually grow into a new colony.
Green Star Polyps are very popular because not only is it fun to watch their little polyps sway in the flow of water, but they are easy to propagate and will spread quickly throughout your aquarium.Corals are part of a biological group known as Cnidaria. Most Cnidaria have a mouth, or mouths, that opens into one big body cavity. Due to the lack of a true digestive system, this cavity acts in its place and after the food is broken down the nutrients are then sent through the rest of the body as food. There is also no excretory system; therefore the waste is sent back through the mouth or secreted into the surrounding water.Tentacles of varying size will usually surround the mouth of Cnidaria. Most Cnidaria have tentacles with stinging cells that can shoot tiny poison darts into their prey or can even be used as a defense mechanism. Some corals lack tentacles and instead cover themselves with a thin layer of mucus and use that to collect bacteria and plankton as food. Some corals even use both of these methods. Cnidaria can either be an individual animal or members of a complex colony. These "Colony Corals" share the food and nutrients taken in by each individual.Corals have tiny living organisms that actually live in their tissue. These are called zooxanthellae and they are the reason why such strong lighting is needed in the saltwater aquarium. These algae-like creatures provide the coral with oxygen and other nutrients that are produced during photosynthesis. During this process, the zooxanthellae take up carbon dioxide and provide nutrients to the coral.Corals can use two different types of defense mechanisms. One of which is a sweeper tentacle wherein the coral reaches its tentacles out to try to damage another coral with nematocysts. The other is when the coral releases a minute amount of toxin into the water to poison another coral within certain proximity.
