Coral reef farming involves extracting a part of a coral colony or free-floating larvae from a reef, and growing them in a nursery until outplanting [5] would be successful. It is commonly referred to as the "gardening method" and has been compared to silviculture as a management practice that mimics natural ecosystems.
Dendronephthya is a genus of soft corals in the family Nephtheidae. [2] There are over 250 described species in this genus. They are sometimes kept in aquariums, but are notoriously difficult to keep, requiring a near constant supply of small foods such as phytoplankton.
