Common name: Rigid Sea Rod

General information

The Rigid Sea Rod, Verongula rigida, is a species of gorgonian coral that is quite popular among reef aquarium enthusiasts. This species is known for its branching, tree-like structure and its vibrant purple coloration, which can add a striking visual element to any reef tank. Gorgonians are a group of corals that are more closely related to soft corals than stony corals, and they have a flexible, internal skeleton made of a substance called gorgonin.

Care

Verongula rigida requires moderate care and is suitable for aquarists with some experience. It thrives in moderate to strong water flow, which helps to prevent sediment accumulation and provides the coral with necessary nutrients and oxygen. This species also needs moderate to high lighting to support the photosynthetic algae, known as zooxanthellae, that live within its tissue. Regular feeding with planktonic foods can supplement its nutritional needs and promote growth.

Symbiosis

While not hosting a wide array of symbiotic relationships like some other corals, Verongula rigida does provide habitat for a variety of small marine organisms. Its branches can serve as a refuge for small fish and invertebrates, offering protection from predators and strong currents.

Habitat

The Rigid Sea Rod is found in the Caribbean Sea and the Gulf of Mexico. It typically inhabits reef slopes and can be found at depths ranging from shallow waters to about 30 meters deep. In the wild, it often grows in areas with strong currents, which is an important consideration for simulating its natural environment in a home aquarium.
