Acanthophyllia Coral Care Info

Acanthophyllia coral care is moderately easy, making this large-polyp stony coral a prized centerpiece for reef aquariums. Known for its oversized fleshy body, bold coloration, and dramatic expansion, Acanthophyllia can become one of the most eye-catching corals in a tank when kept in stable conditions. With proper placement, gentle flow, and regular feeding, it can thrive and show exceptional color and inflation.

Care Requirements

Lighting (PAR Range)

• Low to Moderate lighting
• Ideal PAR: 50–120
• Too much light can cause bleaching or tissue recession

Flow

• Low, gentle flow
• Avoid strong direct flow that can damage fleshy tissue

Placement

• Best placed on the sand bed
• Keep away from sharp rockwork to prevent tissue damage

Aggression

• Peaceful to semi-aggressive coral
• Can extend feeder tentacles, especially at night
• Allow space from nearby corals

Growth Rate

• Slow to moderate growth
• Expands significantly in size when healthy

Feeding

Acanthophyllia corals benefit greatly from regular feeding, which helps improve growth, coloration, and overall health.

• Feed 1–2 times per week
• Accepts mysis shrimp, pellets, and other meaty foods
• Target feeding is recommended
• Turn off flow briefly during feeding for best results

Tank Compatibility

Acanthophyllia corals are best suited for peaceful reef tanks with stable water quality and careful placement.

• Ideal for mixed reefs and LPS coral systems
• Compatible with most reef-safe fish and invertebrates
• Avoid aggressive tank mates that may nip at fleshy tissue
• Provide extra room so the coral can fully expand

Common Problems

• Tissue damage from strong flow or rough placement
• Bleaching from excessive light
• Poor inflation from unstable water parameters
• Stress from aggressive neighbors or sudden changes

Tips for Success

• Place on soft substrate like sand
• Maintain stable alkalinity, calcium, and magnesium
• Keep nutrients balanced
• Acclimate slowly to new lighting
• Feed consistently for best color and expansion
