General information

The Honeycomb Coral, Diploastrea heliopora, is a hardy and visually striking species of stony coral commonly found in reef aquariums. It is known for its distinctive, honeycomb-like skeletal structure, which provides a unique texture and appearance. This coral is a slow-growing, massive species that can form large, dome-shaped colonies over time.

Care

Diploastrea heliopora is relatively easy to care for, making it suitable for both novice and experienced reef keepers. It thrives in stable aquarium conditions with moderate to high lighting and moderate water flow. While it can tolerate a range of water parameters, maintaining consistent levels is crucial for its health and growth. Feeding is not strictly necessary, as it benefits from the symbiotic zooxanthellae within its tissues, but occasional feeding with fine particulate foods can promote faster growth and more vibrant coloration.

Symbiosis

Like many stony corals, Diploastrea heliopora hosts symbiotic algae known as zooxanthellae. These algae live within the coral's tissues and provide it with essential nutrients through photosynthesis, while the coral provides the algae with a protected environment and access to sunlight.

Habitat

In the wild, Diploastrea heliopora is typically found in the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the central and western Pacific Ocean. It prefers reef slopes and lagoons, usually at depths ranging from 3 to 30 meters. This coral is often seen in areas with strong sunlight exposure, which supports its symbiotic algae.
