Common name: Angular Sea Whip

General Information

The Angular Sea Whip or Purple Ribbon Gorgonian, scientifically known as Pterogorgia anceps, is a striking gorgonian coral species found in the Caribbean Sea. This species is known for its unique angular branches, which can display a range of colors from vibrant purple to yellow. The branches of Pterogorgia anceps are flattened and have a distinctive zigzag pattern, making it a popular choice among aquarists seeking to add a dramatic flair to their reef tanks.

In the wild, the Angular Sea Whip plays an important role in the reef ecosystem by providing habitat and shelter for various marine organisms. Its intricate structure offers protection for small fish and invertebrates, while also serving as a substrate for other sessile organisms.

Care

Caring for the Angular Sea Whip in captivity requires attention to water flow and lighting. This species thrives in environments with moderate to high water flow, which helps to keep its branches free from detritus and promotes healthy growth. Lighting should be intense, as Pterogorgia anceps relies on photosynthesis to meet its energy needs.

Placement in the aquarium should be carefully considered to ensure that the coral receives adequate light and flow. It can be positioned in the middle to top areas of the tank, where it can extend its branches into the current.

Diet and Feeding

While the Angular Sea Whip is photosynthetic, it can benefit from supplemental feeding. Offering small planktonic foods, such as rotifers or marine snow, can enhance its growth and coloration. Feeding should be done sparingly, as overfeeding can lead to water quality issues.

Behavior and Compatibility

Pterogorgia anceps is a peaceful coral that poses no threat to other tank inhabitants. It can coexist with a variety of other corals and reef-safe fish. However, care should be taken to avoid placing it too close to aggressive corals that may outcompete it for space or resources.

Health and Common Issues

Ensuring the health of Pterogorgia anceps involves maintaining stable water parameters and providing adequate flow and light. Look for signs of stress, such as tissue recession or discoloration, and address any water quality issues promptly. Regular monitoring and maintenance will help prevent common problems such as algae overgrowth or detritus accumulation on the branches.

Habitat

Pterogorgia anceps is native to the Caribbean Sea, where it inhabits shallow reef environments. It is typically found at depths of up to 30 meters (about 100 feet), thriving in areas with strong currents and plenty of sunlight. This natural habitat can be replicated in captivity by ensuring good water movement and bright lighting.
