Common name: Jania rubens

General information

Jania rubens, commonly known as Red Bushy Algae or Red Jania, is a species of calcareous red algae that is often found in marine aquariums. This algae is appreciated for its attractive bushy appearance and its intense red coloration, which adds a splash of color and diversity to the reef tank. It is a non-invasive species, making it a good choice for aquarists who want to add some natural decor without the risk of it overtaking the tank.

Care

Red Bushy Algae is relatively easy to care for, thriving in a range of lighting conditions from moderate to high. It prefers strong water movement and clean, nutrient-rich water. It can absorb excess nutrients, such as nitrates and phosphates, helping to maintain water quality. Regular pruning may be necessary to keep its growth in check and to ensure it does not shade other inhabitants of the aquarium.

Symbiosis

While Jania rubens does not have any specific symbiotic relationships like those seen in anemones or corals, it does provide a habitat for small invertebrates and microfauna. These organisms can find shelter among its branches, and in turn, they contribute to the tank's biodiversity and cleaning crew by consuming detritus and algae.

Habitat

In the wild, Jania rubens is commonly found in shallow waters, often attached to rocks or other hard substrates. It is widespread in the Mediterranean Sea and the Atlantic coasts of Europe and Africa. In the aquarium, it can be attached to live rock or other structures to mimic its natural environment.
