Common name: Carnation Coral

General information

The Carnation Coral, scientifically known as Dendronephthya rubeola, is a species of soft coral that is highly sought after for its intricate structure and vibrant colors, which can range from reds and pinks to purples and oranges. Unlike many other corals, Dendronephthya spp. do not contain zooxanthellae, the symbiotic algae that provide nutrients to most reef-building corals through photosynthesis. This means they rely entirely on capturing plankton and nutrients from the water column.

Care

Carnation Corals are considered challenging to keep in the home aquarium due to their specific feeding requirements. They need a constant supply of fine particulate food and excellent water quality with low nitrate levels. Strong water movement is also essential to keep these corals healthy, as it aids in the delivery of food and removal of waste products.

Symbiosis

While Dendronephthya rubeola does not engage in the classic symbiotic relationship with zooxanthellae, it may host a variety of small invertebrates within its branches. These can include certain species of commensal crabs and shrimp, which find refuge among the coral's structure.

Habitat

Carnation Corals are typically found in the Indo-Pacific region, often in deeper waters with strong currents. They attach to hard substrates, such as rocks or dead coral, where they can effectively capture food particles brought by the water flow.
