Red Doughnut Coral

The Red Doughnut Coral, scientifically known as Acanthophyllia deshayesiana, is a remarkable species of stony coral belonging to the family Lobophylliidae. This solitary coral is commonly referred to as the flat cup coral, button coral, or doughnut coral due to its distinctive shape and structure. Found predominantly in the western Indo-Pacific Ocean, this species thrives in shallow waters and often resides on sandy or muddy substrates, where it can capture nutrients effectively.

Visually, the Red Doughnut Coral is characterized by its large, disc-shaped polyps that can expand significantly during the day. The corals exhibit vibrant red, orange, and pink hues, often with contrasting patterns that enhance their aesthetic appeal. When fully expanded, the coral can reach impressive diameters, showcasing its unique appearance. The tentacles of the coral are equipped with specialized cells called nematocysts, which allow it to capture small prey such as zooplankton.

In terms of behavior, the Red Doughnut Coral is primarily nocturnal, with its feeding polyps extending at night to maximize feeding opportunities. During the day, it relies on photosynthetic symbiotic algae (zooxanthellae) living within its tissues to produce energy, although it will actively feed on plankton and other small organisms when available. This dual feeding strategy allows the coral to thrive in various environmental conditions.

Red Doughnut Corals prefer stable environments with moderate water flow and light conditions. They are often found in areas with a mix of hard and soft corals, where they can benefit from the diverse ecosystem surrounding them. Their adaptability to different habitats makes them a popular choice for aquarists looking to create vibrant reef displays.

The Red Doughnut Coral requires specific care to thrive in a marine aquarium. Ideal water parameters include a temperature range of 24-28°C, a salinity of 1.020-1.025 ppt, and a pH level between 8.1 and 8.4. Maintaining stable water quality is crucial, as fluctuations can stress the coral and lead to health issues.

Feeding the Red Doughnut Coral is essential for its overall health. It benefits from a diet consisting of finely chopped meaty foods, such as brine shrimp and mysis shrimp, offered several times a week. Additionally, providing quality coral food rich in nutrients will support its growth and vitality. Compatibility-wise, this coral can be housed with a variety of reef-safe fish and invertebrates, but caution should be exercised with aggressive species that may harm it.

Acclimation is vital when introducing the Red Doughnut Coral to a new environment. A slow acclimation process over several hours is recommended to minimize shock. Quarantine should also be considered for new arrivals to prevent the introduction of pests or diseases into the main aquarium. Regular monitoring and maintenance will ensure that this stunning coral remains a centerpiece of any marine display.

The Red Doughnut Coral is suitable for shipping under controlled conditions. It should be packed with care to minimize stress, ideally in a breathable container with adequate moisture. The coral is temperature-sensitive, requiring stable conditions during transit. It is not listed under CITES, allowing for relatively straightforward export processes.
