Common name: double-forked plexaurella

General information

The Slimy Sea Plume, scientifically known as Plexaurella dichotoma, is a species of soft coral belonging to the family Plexauridae. It is characterized by its branching, tree-like structure with a somewhat slimy texture, which is where it gets its common name. The coral exhibits a range of colors from yellow to brown and is often found in reef environments.

Care

Caring for Plexaurella dichotoma in a reef aquarium requires moderate to high water flow and low to moderate lighting conditions. It is a photosynthetic coral, which means it harbors symbiotic algae known as zooxanthellae that help provide nutrients through photosynthesis. However, supplemental feeding with planktonic foods can benefit its growth and health.

Symbiosis

While Plexaurella dichotoma does not have any well-known symbiotic relationships akin to clownfish and anemones, it does provide a habitat for various small invertebrates and fish within its branches, enhancing biodiversity in the reef aquarium.

Habitat

This species is typically found in the Caribbean Sea and adjacent waters. It thrives in a range of depths, often between 10 to 30 meters, where it can form dense thickets on the reef slope. These formations contribute to the complex structure of the reef, offering shelter and living space for a multitude of marine organisms.
