Silk Coral - Red / Orange, in the genus, Scleronepthya sp., are also known as Carnation Corals, Orange Soft Corals, Tree Corals, Strawberry Corals, and Flower Tree Coral They resemble closely the genus Dendronephthya but are actually slightly easier to care for. They are often a deep red, orange, or pink color giving it some variations of its common name. They exhibit high levels of movement with tank currents and have bright, exuberant colors. Carnation Corals are non-photosynthetic so they do not require high levels of light, but do require a strong current in the tank. They will eat plankton the are moving in the current but should also be direct fed specialty food for filter feeding invertebrates. The Carnation Coral is fickle and will only thrive in the right, aforementioned, tank environment. Be warned while housing the Carnation Coral with nudibranchs as some species can be harmful to the coral.
