Common name: Acan Lord

General Information

The Micromussa lordhowensis, commonly known as the Acan Lord or Acan Coral, is a highly sought-after species in the reef aquarium hobby. Known for its vibrant color variations and relatively easy care, this coral has become a favorite among both novice and experienced aquarists. Its fleshy polyps and striking patterns make it a standout addition to any reef tank.

Previously classified as Acanthastrea lordhowensis, this coral underwent a significant taxonomic revision in 2016. Advances in coral research, particularly in genetic studies, revealed that the species was more appropriately placed in the genus Micromussa. This renaming event reflects ongoing efforts by marine biologists to more accurately categorize coral species based on their biological relationships. The change has been widely adopted in the aquarium trade, although many hobbyists still refer to it as "Acan Lord" out of familiarity.

Originally found in the Indo-Pacific region, particularly around the Great Barrier Reef, the Acan Lord has gained popularity due to its adaptability and the stunning array of colors available through selective breeding. In the wild, it typically inhabits sheltered reef slopes and lagoons, where it forms large, encrusting colonies.

Care

Micromussa lordhowensis is considered a hardy coral, making it suitable for aquarists of varying experience levels. It thrives in stable reef environments with moderate lighting and water flow. While it can tolerate a range of conditions, providing optimal parameters will enhance its growth and coloration.

This coral does well in a variety of tank sizes, but it's important to ensure adequate space for its fleshy polyps to expand. Avoid placing it too close to other corals, as it has sweeper tentacles that can sting neighboring species.

Diet and Feeding

Acan Lords are photosynthetic but benefit greatly from supplemental feeding. They can be fed a variety of meaty foods such as mysis shrimp, brine shrimp, and specialized coral foods. Feeding at night when the polyps are extended can encourage growth and intensify coloration.

Behavior and Compatibility

Micromussa lordhowensis is generally peaceful but can exhibit aggression toward nearby corals due to its sweeper tentacles. It's best to provide ample space between it and other corals to prevent damage.

This coral is compatible with a wide range of reef-safe fish and invertebrates, making it a versatile addition to community tanks. However, ensure that tank mates do not pick at its fleshy polyps.

Propagation

Propagation of Acan Lords is typically done through fragging, a process where a piece of the coral is carefully cut and allowed to grow independently. This method is popular among hobbyists seeking to expand their collection or trade with others.

Health and Common Issues

Micromussa lordhowensis is relatively hardy but can be susceptible to tissue recession and bleaching if water conditions are not maintained. Regular monitoring of water parameters and providing a stable environment are crucial for its well-being.

When selecting an Acan Lord, look for healthy, vibrant polyps that are fully extended. Avoid specimens with receding tissue or faded colors, as these may indicate stress or poor health.

Habitat

In the wild, Micromussa lordhowensis is found in the Indo-Pacific, including the Great Barrier Reef and surrounding areas. It typically resides in sheltered reef environments with moderate water movement, where it forms large colonies on reef slopes and lagoons.

Conservation Status

Listed under CITES Appendix II, Micromussa lordhowensis is not currently considered endangered, but its trade is monitored to ensure sustainable practices. Hobbyists are encouraged to purchase aquacultured specimens to minimize impact on wild populations.
