Common name: Starry Cup Coral

General Information

Acanthastrea echinata, commonly known as the Starry Cup Coral or Echinata Coral, is a popular choice among reef aquarium enthusiasts. Known for its vibrant colors and unique patterns, it is often sought after for its striking appearance and relatively forgiving nature, making it an excellent addition to many reef tanks.

In the wild, Acanthastrea echinata is found in various reef environments across the Indo-Pacific region. Its adaptability to different lighting and flow conditions has made it a favorite among hobbyists. While it is not as commonly seen as some other coral species, its growing popularity in the aquarium trade reflects its aesthetic appeal and ease of care.

Care

Acanthastrea echinata is considered moderately easy to care for, making it suitable for aquarists with some experience. It thrives in aquariums that replicate its natural reef environment, with stable water parameters and moderate lighting. The coral's fleshy polyps can expand significantly, so providing ample space around it helps prevent aggression towards neighboring corals.

This species benefits from regular feeding with small meaty foods, such as mysis shrimp or specialized coral foods, to supplement its photosynthetic needs. Maintaining proper calcium, alkalinity, and magnesium levels is essential for its growth and health.

Diet and Feeding

While Acanthastrea echinata is photosynthetic, it also benefits from supplemental feeding. Offering occasional feedings of small, meaty foods like mysis shrimp or finely chopped seafood can promote faster growth and more vibrant coloration. Feeding should be done with care to avoid overfeeding and maintain water quality.

Behavior and Compatibility

Acanthastrea echinata is generally peaceful but can be aggressive towards nearby corals if they encroach on its space. Its sweeper tentacles can extend to sting neighboring corals, so providing adequate spacing is crucial. It is compatible with a wide range of other reef-safe species, making it a versatile choice for community tanks.

Propagation

Propagation of Acanthastrea echinata is typically done through fragging, where a section of the coral is carefully cut and attached to a substrate to grow a new colony. This process requires precision and care to ensure the health of both the parent and the new fragment.

Health and Common Issues

Acanthastrea echinata is relatively hardy but can suffer from poor water quality or insufficient lighting. Monitoring water parameters and ensuring stable conditions are key to preventing issues such as tissue recession or bleaching. Regular observation and maintenance will help keep this coral healthy and thriving.

Habitat

In the wild, Acanthastrea echinata is found in a variety of reef environments, from lagoons to outer reef slopes. It prefers areas with moderate water flow and lighting, which should be replicated in the home aquarium to mimic its natural conditions.
