Common name: Red sea fingers

General information

The Red Finger Soft Coral, scientifically known as Alcyonium glomeratum, is a species of soft coral that is popular among reef aquarium enthusiasts for its ease of care and attractive appearance. This coral is characterized by its red to pinkish hue and finger-like lobes that extend from a central base. It is a non-photosynthetic coral, which means it does not rely on light for its nutrition but instead captures plankton and other small particles from the water column.

Care

Alcyonium glomeratum is considered a hardy species that can thrive in a variety of tank conditions. It prefers moderate to low water flow and indirect lighting. Since it is a filter feeder, it benefits from the occasional feeding of planktonic foods or finely minced seafood. Maintaining good water quality and stable parameters is crucial for the health of this coral.

Symbiosis

While Alcyonium glomeratum does not have any well-known symbiotic relationships like those seen in clownfish and anemones, it can provide a habitat for small invertebrates and microfauna within the reef aquarium. These organisms can benefit from the shelter provided by the coral's structure.

Habitat

The natural habitat of the Red Finger Soft Coral is the rocky subtidal zones of the North Atlantic Ocean, where it is often found in areas with strong currents. In the aquarium, it can be placed on live rock where it can attach and spread. It is important to allow enough space for growth and to avoid placing it too close to other corals, as it can be aggressive and overgrow its neighbors.
