Common name: Scinaia complanata

General information

Scinaia complanata is a species of marine red algae that is often sought after by reef aquarium hobbyists for its attractive appearance and utility in the tank. It is characterized by its flat, fan-shaped thalli that can range in color from deep red to purple. This algae is not only aesthetically pleasing but also serves as a natural nutrient exporter, helping to maintain water quality by absorbing excess nutrients like nitrate and phosphate.

Care

Caring for Scinaia complanata requires a stable marine aquarium with moderate to high lighting and good water flow to mimic its natural environment. It prefers a tank with a mature biological filter and can benefit from the addition of trace elements and nutrients to support its growth. Regular pruning may be necessary to keep its growth in check and to prevent it from overshadowing other inhabitants of the tank.

Symbiosis

While Scinaia complanata does not have any known obligate symbiotic relationships, it can provide a habitat for small invertebrates and microfauna. These organisms can find refuge among its branches and contribute to the overall biodiversity of the aquarium.

Habitat

Scinaia complanata is typically found in shallow, subtidal zones of tropical and subtropical seas. It attaches to hard substrates such as rocks and coral rubble, often in areas with strong water movement that facilitates the exchange of nutrients and gases.
