there are over 250 species of Carnation Tree Coral, including this peach-colored specimen. according to Hong Kong's Agriculture, Fisheries and Conservation Department, "Dendronephthya corals lack symbiotic zooxanthallae and thus do not depend on photosynthesis for producing food. This allows them to inhabit deeper water with lower light attenuation. With the aid of their contractable tentacles, they actively filter and feed on phytoplankton, protozoa and particulate organic carbon from the water which travels in close proximity to them"
