Common name: Peacock's Tail

General information

Stypopodium zonale, commonly known as Peacock's Tail or Mermaid's Fan, is a species of marine brown algae that is popular among reef aquarium hobbyists for its unique fan-like appearance and its ability to help control nutrient levels in the tank. This alga is characterized by its dark olive-green to brown thalli, which are leaf-like structures that can grow quite large under optimal conditions.

In the wild, Stypopodium zonale is often found in shallow, rocky reef environments where it forms dense mats. It is a hardy species that can tolerate a range of lighting conditions, making it a versatile addition to many types of saltwater aquariums.

Care

Peacock's Tail requires moderate to high lighting to thrive in the aquarium setting. It is important to provide it with a stable environment with consistent water quality. This alga benefits from the addition of trace elements and iodine, which support its growth and health. It can be easily propagated by fragmentation, allowing hobbyists to share or trade with others.

Symbiosis

While not hosting a wide array of symbiotic relationships like some corals or anemones, Stypopodium zonale does provide a habitat and food source for a variety of small invertebrates and fish. Its dense structure offers shelter and protection for these creatures.

Habitat

Stypopodium zonale is native to the Atlantic Ocean, ranging from the Caribbean to the coast of West Africa. It typically inhabits reef flats and rocky substrates in shallow waters where it receives ample sunlight. In the aquarium, it should be placed in areas with strong water movement to mimic its natural habitat and prevent detritus from accumulating on its surface.
