The Clove Polyp is commonly known as eight tentacle polyps, or encrusting polyps. It is colonial in nature and mostly found attached to a single piece of live rock. The Clove Polyp may also form mats or clumps. It is not really difficult to maintain and requires medium light along with medium flow current of water within the aquarium. It should be kept far away from stinging corals, as the Clove Polyp can be stung by aggressive corals, and therefore need adequate space between themselves and corals. Sometimes, the Clove Polyp may harm zoanthid anemones, if kept adjacent to it. It thrives well in addition of trace amount of iodine into the water. The Clove Polyp grows rapidly in the established reef aquarium by encrusting over adjacent rock work or even other corals. It possesses symbiotic algae, zooxanthellae, in its tissue which helps in manufacturing food and provides energy and nutrition to the coral. Also, the additional feeding is not required but weekly feedings of micro plankton or food designed for feeding invertebrates does wonders for the Clove Polyp. Its amazing colors make this a valuable specimen which is stunning and outstanding in your aquarium. On retracting, the polyps gets closed in such a way that even its closed heads are visible. It breeds easily and rapidly, and may grow over everything adjacent to it, therefore place the Clove Polyp in a spacious region of your aquarium and also away from the corals. It grows well in a temperature range of 72 to 78 degrees Fahrenheit, and pH of 8.10-8.40.
Cylindrical upright tube like polyps rise from a creeping stolon that attaches to the substrate.The polyps will sometimes completely retract into the calyces.Tentacles are feathery in appearance.Moderate to high lighting and low to moderate flow is needed.Low in aggressiveness to other corals and is moderately hardy in captivity.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 digestivesystem, this cavity acts in its place and after the food is broken down thenutrients are then sent through the rest of the body as food. There is also noexcretory system; therefore the waste is sent back through the mouth or secretedinto the surrounding water.Tentacles of varying size will usually surround the mouth of Cnidaria. Most Cnidariahave tentacles with stinging cells that can shoot tiny poison darts into their preyor can even be used as a defense mechanism. Some corals lack tentacles and insteadcover themselves with a thin layer of mucus and use that to collect bacteria andplankton as food. Some corals even use both of these methods. Cnidaria can either bean individual animal or members of a complex colony. These "Colony Corals" share thefood and nutrients taken in by each individual.Corals have tiny living organisms that actually live in their tissue. These arecalled zooxanthellae and they are the reason why such strong lighting is needed inthe saltwater aquarium. These algae-like creatures provide the coral with oxygen andother nutrients that are produced during photosynthesis. During this process, thezooxanthellae take up carbon dioxide and provide nutrients to the coral.Corals can use two different types of defense mechanisms. One of which is a sweepertentacle wherein the coral reaches its tentacles out to try to damage another coralwith nematocysts. The other is when the coral releases a minute amount of toxin intothe water to poison another coral within certain proximity.
