Common name: yellow sea whip

General information

The Yellow Sea Whip, scientifically known as Pterogorgia citrina, is a species of gorgonian coral that is popular among reef aquarium enthusiasts for its striking yellow to yellow-green coloration and unique, feather-like structure. This coral belongs to the family Gorgoniidae and is native to the Caribbean Sea and adjacent waters.

Unlike stony corals, gorgonians are flexible and sway with the currents, adding a dynamic element to the aquarium. Pterogorgia citrina is a photosynthetic species, hosting symbiotic algae known as zooxanthellae within its tissue, which provide the coral with nutrients through photosynthesis.

Care

Yellow Sea Whip corals require moderate to strong water flow and moderate lighting to thrive in captivity. They are relatively hardy and can adapt to a range of conditions, but stability is key to their long-term health. Target feeding is not necessary due to their symbiotic relationship with zooxanthellae, but they can benefit from occasional feedings of planktonic foods.

Symbiosis

Pterogorgia citrina, like many gorgonians, hosts symbiotic zooxanthellae that provide the majority of its nutritional needs through photosynthesis. This coral may also provide a habitat for small invertebrates, such as certain species of brittle stars and amphipods, which can help keep the coral clean from debris and algae.

Habitat

In the wild, Pterogorgia citrina is typically found in shallow waters, often in reef crests and fore-reef slopes where water movement is abundant. They are usually attached to hard substrates and can form dense colonies. Their natural range extends throughout the Caribbean Sea, including the Bahamas, Florida Keys, and northern coast of South America.
