The Pagoda Cup is a large polyp stony coral, which grows in a conical or cup shape, commonly referred as pagoda cup, turban, vase, or scroll corals. It can grow horizontally as well as vertically, and a number of these species may extend their polyps during the day or night while thriving in the aquarium. The Pagoda Cup is quite easy to care for and this makes it a very good choice for a beginner aquarist. It is considered a peaceful reef inhabitant, which does not bother corals that are placed in close proximity to it. The Pagoda Cup requires moderate lighting combined with moderate water movement within the aquarium. Also, the addition of calcium, strontium, and other trace elements also benefits the growth of this beautiful species in the tank. The Pagoda Cup should be kept in a tank not less than 20 gallons. It undergoes photosynthesis and manufactures food using the zooxanthellae that dwells inside its tissue. The Pagoda Cup also directly absorbs some nutrients from the water and feeds on micro zooplankton. The Pagoda Cups with highly convoluted or thin plates are the most difficult to care for. It grows quickly and propagates easily in the tank, which makes it a valuable addition to any reef tank. The Pagoda Cup requires medium light level combined with a medium water movement within the aquarium.
The Pagoda Cup coral has numerous polyps extending from its cup-like base.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. Most "Hard Corals" should not be placed within reach of another coral.
