Common name: Acan Coral

General Information

Acanthastrea hemprichii, commonly known as the Acan Coral, is a popular and visually striking species in the reef aquarium hobby. Known for its vibrant color variations, which can include reds, oranges, greens, and blues, this coral is a favorite among aquarists looking to add a splash of color to their tanks. Its fleshy polyps and compact growth form make it an attractive addition to any reef setup.

In the wild, Acanthastrea hemprichii is found in the Indo-Pacific region, inhabiting shallow reef environments. Its ability to thrive in a range of lighting and flow conditions makes it a versatile choice for both novice and experienced reef keepers.

Care

Acan Corals are relatively easy to care for, making them suitable for hobbyists of all experience levels. They thrive in stable water conditions with moderate lighting and flow. These corals benefit from regular feeding, which can enhance their growth and coloration. Offering a variety of foods, such as mysis shrimp, brine shrimp, and specialized coral foods, will help meet their nutritional needs.

When placing Acanthastrea hemprichii in your aquarium, consider its need for space. While it can tolerate a range of lighting intensities, providing moderate lighting will help maintain its vibrant colors without risking bleaching. Ensure there is enough space between it and other corals to prevent aggression, as Acans can extend their sweeper tentacles.

Diet and Feeding

Acanthastrea hemprichii is photosynthetic but will greatly benefit from supplemental feeding. Target feeding with meaty foods like mysis shrimp or brine shrimp can promote faster growth and more intense coloration. Feeding once or twice a week is typically sufficient, depending on the coral's response and the overall nutrient levels in the tank.

Behavior and Compatibility

Acan Corals are generally peaceful but can exhibit aggression towards nearby corals if they feel threatened. Their sweeper tentacles can extend several centimeters, so it's important to provide adequate space between them and other corals.

They are compatible with a wide range of reef-safe fish and invertebrates. However, be cautious with species that might nip at coral polyps, such as some butterflyfish and angelfish.

Propagation

Propagation of Acanthastrea hemprichii is commonly done through fragging. This involves cutting a section of the coral with a clean, sharp tool and allowing it to heal in a stable environment. With proper care, the frags will grow into new colonies, making this coral a great choice for hobbyists interested in coral propagation.

Health and Common Issues

Acanthastrea hemprichii is generally hardy but can be susceptible to common coral ailments such as tissue recession and bleaching if not properly cared for. Maintaining stable water parameters and avoiding drastic changes in lighting or flow can help prevent these issues. Regular observation and prompt response to any signs of distress can ensure the long-term health of this coral.

When selecting an Acan Coral, look for specimens with full, fleshy polyps and vibrant coloration. Avoid corals with signs of tissue recession or bleaching, as these may indicate underlying health issues.

Habitat

In the wild, Acanthastrea hemprichii is found in the Indo-Pacific region, often inhabiting shallow reef environments with moderate water flow. These corals thrive in areas where they can receive ample light and nutrients, allowing them to maintain their symbiotic relationship with zooxanthellae.
