Red Plate Coral

Heliofungia actiniformis, commonly known as the Red Plate Coral, is a remarkable solitary mushroom coral belonging to the family Fungiidae. This species is characterized by its large, plate-like structure that can reach significant sizes, making it a striking feature in any marine aquarium. Typically found in shallow waters of the Indo-Pacific region, this coral thrives in environments where it can receive adequate sunlight, thanks to its symbiotic relationship with zooxanthellae, which provide it with essential nutrients through photosynthesis.

The appearance of the Red Plate Coral is truly captivating. Its surface is often adorned with vibrant hues of red, orange, and pink, which can vary depending on the individual and the conditions of its environment. The polyp extends from the central disc, displaying a series of tentacles that can capture plankton and small organisms, further supplementing its diet. Behaviorally, H. actiniformis is generally solitary, though it can be found in small clusters, particularly in areas where conditions are favorable.

In terms of habitat, Red Plate Coral prefers sandy substrates and can often be seen resting on the ocean floor. It is commonly found in coral reefs, lagoons, and on slopes where light penetration is optimal. However, wild populations of Heliofungia actiniformis face significant threats from climate change, coral bleaching, and over-collection for the aquarium trade, which has led to its classification as a vulnerable species by the IUCN. Conservation efforts are essential to ensure the sustainability of this beautiful coral in its natural habitat and the aquarium trade.

Overall, the Red Plate Coral is not only an aesthetic marvel but also an ecological treasure, playing a crucial role in the health of coral reef ecosystems.

When caring for Heliofungia actiniformis, it is vital to maintain stable water parameters. The ideal temperature range is between 24°C to 28°C, with a salinity of 1.023 to 1.025 ppt. The pH should be kept between 8.1 and 8.4 to provide optimal conditions for growth. A minimum tank size of 100 liters is recommended to accommodate its growth and provide ample space for water circulation.

Feeding the Red Plate Coral requires attention to both its photosynthetic needs and supplemental feeding. While it derives energy from its symbiotic zooxanthellae, offering small pieces of meaty foods, such as brine shrimp or zooplankton, a few times a week can enhance its health and vibrancy. Compatibility with other marine species is generally good; however, it is best to avoid aggressive tankmates that may harm or compete for space.

Acclimation is crucial when introducing this coral to a new environment. A slow acclimation process, typically lasting 2-3 hours, is recommended to minimize stress. Quarantine procedures should be in place to prevent the introduction of parasites and diseases. Monitoring for signs of stress, such as retraction of polyps or color fading, will help ensure a healthy and successful life for this exquisite coral.

The Red Plate Coral is suitable for shipping with proper care. It should be packed in a sturdy container with sufficient water to cover the coral, ensuring minimal movement during transit. Packing density should be moderate to prevent damage. Temperature sensitivity is a concern; thus, maintaining a stable temperature between 24°C to 28°C during transport is essential. Heliofungia actiniformis is not listed under CITES, but awareness of local regulations is recommended to ensure compliance.
