Common name: Caulerpa brachypus

General information

Caulerpa brachypus, commonly known as Fern Caulerpa or Green Feather Algae, is a species of green macroalgae that is popular among reef aquarium hobbyists for its attractive fern-like appearance. This species is part of the Caulerpaceae family and is known for its fast growth and ability to absorb excess nutrients from the water, which can help in controlling algae blooms and maintaining water quality.

Care

Caulerpa brachypus requires moderate lighting and a stable environment to thrive. It can be easily propagated by fragmentation, making it a sustainable choice for aquarists. However, it is important to keep its growth in check, as it can overtake other sessile organisms in the aquarium if left unmanaged. Regular pruning is recommended to maintain its size and shape within the tank.

Symbiosis

While not known for hosting or forming direct symbiotic relationships with marine animals, Caulerpa brachypus does play a role in the ecosystem by providing shelter and food for small invertebrates and fish larvae. Its dense structure can create microhabitats within the aquarium.

Habitat

Caulerpa brachypus is found in tropical and subtropical oceans around the world. It typically grows on rocky substrates and coral rubble in shallow waters. In the wild, it can be found at various depths, often forming dense mats that serve as important ecological components of their native habitats.
