Common name: colorful sea rod

General information

The Red Tree Gorgonian, scientifically known as Diodogorgia nodulifera, is a striking species of soft coral known for its unique branching structure and vibrant red coloration. Unlike stony corals, gorgonians belong to the subclass Octocorallia, which means they have eight tentacles on each polyp. This species is often sought after by advanced aquarists due to its ornamental value and the dynamic structure it adds to the reef aquarium.

Care

Caring for Diodogorgia nodulifera can be challenging and is generally recommended for experienced hobbyists. This gorgonian requires moderate to strong water flow to prevent detritus from settling on its branches, which can lead to tissue necrosis. It also needs low to moderate lighting, as too intense light can stress the coral. Feeding is critical for this species; it benefits from regular feedings of fine particulate foods, like phytoplankton and zooplankton, to supplement its photosynthetic nutrition.

Symbiosis

While Diodogorgia nodulifera does not have the same level of symbiosis with fish as some anemones do, it does host a variety of small invertebrates. These include commensal brittle stars and shrimp that may live among its branches, benefiting from the coral's structure for protection and feeding opportunities.

Habitat

The Red Tree Gorgonian is typically found in the Western Atlantic, from the Bahamas and Florida to the northern coast of South America. It inhabits reef slopes and walls, usually at depths ranging from 15 to 30 meters, where the water flow is strong enough to deliver a steady supply of planktonic food.
