The Scroll Coral is a small polyp stony (SPS) coral, which is commonly known as Pagoda, Turban, Vase, or Bowl Coral. Since it grows in a conical or cup shape while living on the reef, it is named aptly as the Cup Coral. The Scroll Coral features a vibrant yellow colored body, which adds a beautiful splash of color into the aquarium. Depending on the conditions that it is exposed to, it grows horizontally and vertically as well. The Scroll Coral is considered a peaceful reef inhabitant and doesn?t bother other corals that are placed in close proximity to it. Since it grows quickly, it needs ample space that allows it to flourish well in the tank. The Scroll Coral requires moderate lighting combined with moderate water movement. It also requires the addition of calcium, strontium, and other trace elements in the water for its continued good health. The Scroll Coral should be fed with brine shrimp or plankton, and its polyps expand in moderate current during late afternoon in shaded areas and at night, since it is nocturnal. The Scroll Coral undergoes photosynthesis and manufactures food and energy using zooxanthellae that dwells inside its tissue.
Common names: scroll, ruffled ridgeColonies are typically leaf like, or may be massive, columnar or branchyPolyps are circular and immersed to tubular.Heavy dense skeleton.Moderate to strong lighting, moderate water flow.Very hardy and non-aggressive.Excellent coral for beginners.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. Most "Hard Corals"should not be placed within reach of another coral.
