Many soft corals are easily collected in the wild for the reef aquarium hobby, as small cuttings are less prone to infection or damage during shipping than stony corals. Nevertheless, home-grown specimens tend to be more adaptable to aquarium life and help conserve wild reefs.
There are two main classifications for corals: hard coral (scleractinian and stony coral) [13] which form reefs by a calcium carbonate base, with polyps that bear six stiff tentacles, [14] and soft coral (Alcyonacea and ahermatypic coral) [13] which are pliable and formed by a colony of polyps with eight feather-like tentacles.

Litophyton arboreum, also known as broccoli coral, is a common soft coral found from the Red Sea to the Western Pacific. It grows up to 80 cm, usually on seaward reef slopes or hard bottoms. The color of L. arboreum varies from pale olive-green to yellow or grey. L. arboreum are anthozoans in the order Alcyonacea in the family Nephtheidae.
Coral reefs deliver ecosystem services for tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at anywhere from US$30–375 billion (1997 and 2003 estimates) [14] [15] to US$2.7 trillion (a 2020 estimate) [16] to US$9.9 trillion (a 2014 estimate).

Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial.
Hermatypic corals are those corals in the order Scleractinia which build reefs by depositing hard calcareous material for their skeletons, forming the stony framework of the reef. Corals that do not contribute to coral reef development are referred to as ahermatypic (non-reef-building) species.
Soft corals and gorgonians: Alcyonium digitatum Mushroom corals: Colonial and diverse, with polyps almost completely embedded in thick fleshy coenosarc. Gorgonians have a horny skeleton. Zooxanthellate or azooxanthellate. [2] Worldwide, mostly in tropical and subtropical waters, associated with coral reefs and in deep sea. [2] Octocorallia ...
SMEs are characterized by carbonate reefs, which support many species. Estimates suggest that coral reefs alone may host between 1-9 million species. The three main types of reef formations are: [8] Fringing Reefs: attached to the shore; Barrier Reefs: separated from the mainland by a lagoon; Atoll Reefs: ring-shaped reefs surrounding a lagoon
