This arrangement allows the coral to grow quickly, which helps in building enormous reefs, provided they remain undamaged or impacted by human populations. e.src = u; Snappers are generally non-aggressive fish that do well in very large saltwater community tanks. Polyp type corals like Zoanthids, green star polyps, clove polyps, and pulsing Xenia, can add movement, and can quickly cover barren rocks. Modest lights then with high water flow and heavy feeding will grow corals amazingly fast. These skeletons, made from calcium carbonate, protect the coral animals from predators and also offer a substrate on which new coral polyps can attach themselves. Other corals can give out a nasty sting with their tentacles, so the same precautions are recommended. This is a frost sensitive specimen which can be killed if temperatures drop below 40 degrees Fahrenheit (4 C.). For simplicity sake we will discuss these as both wall and branching hammer corals.

Eventually this will lead to the coral splitting, expanding or whatever it specifically does to grow. 3. Corals form many different types of reef structures. Metal halides. The corals on a reef are further cemented together by organisms like coralline algae, and physical processes like waves washing sand into spaces in the reef. This creates the limestone skeleton that grows outward and upward. } else { By measuring and examining the thickness of each band, marine scientists can estimate how much the corals grew during a given time period. Encrusting corals grow as a thin layer against the substrate.
