Common name: Leafy caulerpa

General information

Caulerpa prolifera, commonly known as Proliferating Caulerpa or Green Feather Algae, is a species of green macroalgae that is popular among reef aquarium hobbyists for its attractive appearance and utility in nutrient control. It is characterized by its feather-like fronds that emerge from long, runner-like stolons, giving it a distinctive look that can add a natural and lush feel to a reef tank.

Care

Caulerpa prolifera is relatively easy to maintain in a reef aquarium, provided it is given adequate lighting and nutrients. It can be a useful addition to a refugium, where it helps to absorb excess nutrients like nitrates and phosphates, thereby reducing the likelihood of nuisance algae outbreaks. However, it is important to keep its growth in check, as it can become invasive and overtake other tank inhabitants if left unmanaged.

Symbiosis

While not involved in the classic symbiotic relationships seen with corals and fish, Caulerpa prolifera does play a role in the ecosystem of a reef tank. It provides a habitat for small invertebrates and can be a grazing area for herbivorous fish, contributing to the overall biodiversity and stability of the aquarium environment.

Habitat

In the wild, Caulerpa prolifera is found in a variety of marine environments, from shallow sandy bottoms to rocky reef areas. It is widely distributed in tropical and subtropical seas and is known for its ability to adapt to different light and flow conditions, making it a versatile species for aquarium use.
