The Flower Dendro Coral (Dendronephthya sp.), also known as the Sun Coral, is ironically, non-photosynthetic and relies on filter-feeding to receive nutrients. They can be fed carnivorous preparations, such as frozen mysis or coral food. They prefer caves or overhangs, and may have to be trained to have polyp extension during the day - This can be achieved by offering food during the day. Overtime, the coral will retain coral extension during the day, expecting food.
