Common name: Aculeus Staghorn Coral

General Information

The Aculeus Staghorn Coral, scientifically known as Acropora aculeus, is a captivating addition to any reef aquarium. Known for its striking, intricate branches that can create a stunning visual display, this coral is a favorite among advanced hobbyists. Its vibrant colors, ranging from shades of green to blue and even purple, make it a sought-after species for adding diversity and beauty to marine tanks.

Acropora aculeus is part of the Acroporidae family, which includes some of the fastest-growing and most structurally complex corals. This species is often found in shallow reef environments, where it contributes to the reef's structural complexity, providing habitat for a variety of marine organisms.

Care

Caring for Acropora aculeus requires a commitment to maintaining stable, high-quality water conditions. It thrives in well-established reef aquariums with strong lighting and water flow to mimic its natural habitat. This coral is sensitive to fluctuations in water parameters, so regular monitoring and adjustments are crucial.

Diet and Feeding

Acropora aculeus is a photosynthetic coral, relying primarily on the symbiotic relationship with zooxanthellae algae living in its tissues. This relationship allows it to derive most of its energy from light. However, supplemental feeding with coral foods, such as phytoplankton and amino acids, can support its growth and coloration.

Behavior and Compatibility

This coral species is generally peaceful but requires adequate space to grow without competition from neighboring corals. It can be sensitive to aggressive corals that may encroach on its territory, so careful placement is necessary.

Reproduction

Acropora aculeus can reproduce both sexually and asexually in the wild. In aquariums, propagation is typically achieved through fragging, where branches are carefully cut and attached to a substrate to grow new colonies.

Symbiosis

The symbiotic relationship between Acropora aculeus and its zooxanthellae is fundamental to its survival and growth. This mutualistic relationship allows the coral to thrive in nutrient-poor waters by converting light into energy.

Health and Common Issues

Maintaining the health of Acropora aculeus involves ensuring stable water parameters, including calcium, alkalinity, and magnesium levels. It is susceptible to coral bleaching if exposed to stressors such as high temperatures or poor water quality. Regular inspections for pests and diseases, such as red bugs or tissue necrosis, are recommended.

Habitat

Acropora aculeus is found in the Indo-Pacific region, thriving in shallow reef environments with strong water movement and plenty of sunlight. These conditions are essential for its photosynthetic processes and structural growth.

Conservation Status

Listed under CITES Appendix II, Acropora aculeus is not necessarily threatened with extinction but requires controlled trade to ensure its survival. Conservation efforts focus on protecting reef habitats and promoting sustainable collection practices in the aquarium trade.
