General information

The Colonial Leather Coral, Parerythropodium hibernicum, is a soft coral species known for its encrusting growth form and leathery texture. It is a part of the Alcyoniidae family, which includes various soft corals that are popular in the reef aquarium hobby. This species is not as commonly kept as some other soft corals, but it can be a unique and attractive addition to a reef tank.

Care

Parerythropodium hibernicum is a hardy coral that can adapt to a range of lighting conditions, from moderate to high. It benefits from gentle to moderate water flow, which helps to remove waste products and deliver nutrients. This coral does not have a high demand for feeding, as it hosts symbiotic zooxanthellae that provide it with most of its nutritional needs through photosynthesis. However, occasional feeding with microplankton or coral foods can promote growth and health.

Symbiosis

Like many soft corals, Parerythropodium hibernicum has a symbiotic relationship with zooxanthellae, microscopic algae that live within its tissues. The zooxanthellae photosynthesize, producing oxygen and organic compounds that nourish the coral. In return, the coral provides the algae with a protected environment and the compounds necessary for photosynthesis.

Habitat

Parerythropodium hibernicum is found in the Indo-Pacific region, typically in shallow waters on reef slopes or in lagoons. It prefers areas with strong light and some water movement, which are conditions that can be replicated in a home aquarium to support its growth and health.
