Common name: Moon Coral

General Information

The Moon Coral, scientifically known as Dipsastraea faviaformis, is a popular choice among reef aquarists for its striking appearance and relatively easy care requirements. This coral is renowned for its vibrant colors and unique, rounded polyp formations that resemble the surface of the moon, hence its common name. Moon Corals are often sought after for their ability to add texture and color to reef aquariums.

Moon Corals play a significant role in reef conservation and hobbyist circles due to their aesthetic appeal and their contribution to the biodiversity of captive reef ecosystems. They are an excellent choice for both beginner and experienced aquarists looking to enhance the beauty of their tanks without the challenges posed by more delicate coral species.

Physically, Dipsastraea faviaformis is characterized by its large, fleshy polyps and a range of colors including reds, greens, blues, and purples. These corals are often confused with species within the Acanthastrea genus. However, their distinctive moon-like surface and polyp arrangement can help in differentiating them from similar species.

Care

Moon Corals are moderately easy to care for, making them suitable for aquarists who have some experience with coral care. They thrive in stable water conditions with moderate lighting and water flow. These corals are photosynthetic but can benefit from supplemental feeding of small meaty foods like mysis shrimp or coral-specific pellets to enhance their growth and coloration.

When placing Moon Corals in the aquarium, ensure they have enough space to expand their polyps without being overshadowed or outcompeted by more aggressive coral species. Their placement should allow for adequate water flow to prevent detritus buildup around their base.

Diet and Feeding

Dipsastraea faviaformis is primarily photosynthetic but will benefit greatly from occasional feeding. In the wild, they capture planktonic food particles, and in captivity, they can be fed with small meaty foods such as brine shrimp, mysis shrimp, or specialized coral foods. Feeding should be done once or twice a week to supplement their photosynthetic nutrition.

Behavior and Compatibility

Moon Corals are generally peaceful but possess sweeper tentacles that can extend to capture food and defend against encroaching corals. It's important to provide them with sufficient space to prevent potential aggression towards neighboring corals.

They are compatible with a wide range of reef-safe fish and invertebrates, making them a versatile addition to community reef tanks. However, care should be taken to avoid placing them too close to other corals that might provoke their defensive behavior.

Propagation

Propagation of Moon Corals can be achieved through fragging, a method where a piece of the coral is carefully cut and allowed to grow into a new colony. This process requires precision and care to ensure the health of both the mother colony and the new frag.

Health and Common Issues

Moon Corals are generally hardy, but like all corals, they require stable water parameters and good husbandry to thrive. Common issues include tissue recession and bleaching, often caused by poor water quality or inadequate lighting. Regular monitoring and maintenance of water conditions, along with appropriate lighting, can prevent these problems.

When selecting a Moon Coral, look for specimens with vibrant colors and full polyp extension. Avoid corals with visible tissue recession or signs of bleaching.
