Acanthophyllia is a genus of large, solitary, and often beautifully colored corals. These corals are commonly known as “Acanthophyllia corals” or “meat corals,” and they are popular in marine aquariums due to their striking appearance and unique characteristics.

Physical Characteristics

• Structure: Acanthophyllia corals have a distinct, dome-shaped body that can reach impressive sizes, often growing to several inches in diameter. They typically have a single mouth located at the center of the coral, surrounded by a ring of tentacles.
• Tentacles: The tentacles are long, fleshy, and often colorful, extending out during feeding times or when the coral is disturbed. The tentacles can be retracted completely into the coral body, giving it a smooth, rounded appearance.
• Coloration: Acanthophyllia corals are known for their vibrant colors, which can include hues of red, orange, green, and purple. The coloration can be affected by factors like lighting, water quality, and overall health.

Habitat

• Distribution: Acanthophyllia species are primarily found in the warm waters of the Indo-Pacific region. They inhabit reef environments, often located in shallow lagoons and on outer reef slopes where they can receive ample light and water flow.
• Symbiotic Relationships: Like other corals, Acanthophyllia has a symbiotic relationship with zooxanthellae, the photosynthetic algae that live within their tissues. This relationship provides the coral with energy and contributes to its vibrant colors.

Care in Aquariums

• Lighting: Acanthophyllia corals prefer moderate lighting conditions. While they benefit from some light due to their symbiotic algae, excessive light can lead to stress and bleaching. Lighting systems like LED or T5 fluorescent lights are commonly used, with moderate intensity.
• Water Flow: They thrive in low to moderate water flow. Strong currents can cause damage to their delicate tentacles, while low flow may lead to detritus buildup.
• Water Parameters: Ideal conditions for Acanthophyllia include:
  • Temperature: 75-82F (24-28C)
  • Salinity: 1.024-1.026
  • pH: 8.1-8.4
  • Alkalinity: 8-12 dKH Maintaining stable water parameters is essential for their health and growth.

Feeding

Acanthophyllia corals are primarily carnivorous and rely on both photosynthesis and direct feeding. They can be fed small meaty foods like mysis shrimp, brine shrimp, and finely chopped seafood. Target feeding is recommended, especially during the evening when they are more active and their tentacles are extended.

Behavior and Compatibility

• Aggression: Acanthophyllia corals can be territorial and may exhibit aggression towards nearby corals, especially if they come into contact. Its crucial to provide adequate space between them and other species to minimize potential stinging.
• Growth: They are relatively slow-growing corals, and while they can form large colonies over time, patience is needed for them to establish themselves in an aquarium setting.

These corals are for saltwater aquariums only.
