Common name: Bent Sea Rod

General Information

The Bent Sea Rod (Eunicea flexuosa) is a striking gorgonian coral commonly found in the shallow waters of the Caribbean Sea. Known for its distinctive, flexible branches that sway gracefully with the ocean currents, this coral adds a dynamic and natural aesthetic to reef aquariums. Unlike many stony corals, gorgonians like the Bent Sea Rod lack a rigid calcium carbonate skeleton, which allows them to bend and flex with the water flow.

In the aquarium trade, the Bent Sea Rod is appreciated for its hardiness and adaptability, making it a popular choice among hobbyists looking to diversify their coral collection. Its unique appearance and movement can enhance the visual appeal of any reef tank, providing both aesthetic beauty and a natural habitat for various marine organisms.

Care

Caring for the Bent Sea Rod is relatively straightforward, making it suitable for aquarists with moderate experience. This coral thrives in well-established reef tanks with stable water parameters. It prefers moderate to high water flow, which helps keep its branches clean and free of detritus. While it is photosynthetic, supplemental feeding with planktonic foods can promote optimal health and growth.

Placement in the aquarium should allow for adequate water movement around its branches. It is best positioned in the middle to upper levels of the tank, where it can receive sufficient light and flow. Regular monitoring and maintenance of water quality are essential to prevent algae growth, which can smother the coral.

Diet and Feeding

As a photosynthetic coral, the Bent Sea Rod derives much of its energy from symbiotic zooxanthellae algae living within its tissues. However, it also benefits from supplemental feeding. Offering a mix of microplankton and other fine particulate foods several times a week can enhance its growth and vitality.

Behavior and Compatibility

The Bent Sea Rod is generally peaceful and can be housed with a wide variety of reef-safe fish and invertebrates. Its flexible branches provide shelter and habitat for small fish and invertebrates, contributing to the overall biodiversity of the aquarium. It does not exhibit aggressive behavior but should be placed with enough space from other corals to prevent overgrowth or shading.

Symbiosis

The Bent Sea Rod has a symbiotic relationship with zooxanthellae algae, which live within its tissues and provide it with energy through photosynthesis. This mutualistic relationship is crucial for the coral's survival and growth, particularly in nutrient-poor environments where it naturally occurs.

Health and Common Issues

In captivity, the Bent Sea Rod can thrive for many years with proper care. Maintaining clean water conditions and preventing algal overgrowth are key to its health. Regularly inspect the coral for signs of stress, such as tissue recession or discoloration, which could indicate water quality issues or insufficient flow.

When selecting a Bent Sea Rod, look for specimens with vibrant, healthy tissue and no signs of damage or disease. Avoid corals with excessive algae or detritus accumulation on their branches.

Habitat

Eunicea flexuosa is commonly found in the Caribbean Sea, inhabiting shallow reef environments where it benefits from strong water movement and ample sunlight. It typically grows in areas with moderate to strong currents, which help keep its branches free from sediment and debris.
