🌿 Habitat & Tank Setup

• Placement: Best positioned on the substrate with ample space on all sides to allow full tissue expansion. Avoid placing on rough or sharp surfaces to prevent tissue abrasion.

• Lighting: Prefers moderate to slightly lower diffuse lighting. May tolerate direct lighting when placed deeper in the water column.

• Water Flow: Thrives in gentle to moderate, indirect water movement. Excessive current can cause the coral to remain contracted.

🌊 Water Parameters

Maintaining stable water conditions is crucial for the health of Trachyphyllia corals:​

• Temperature: 75–80°F (24–27°C)

• Salinity: 1.024–1.026

• pH: 8.1–8.4

• Alkalinity: 8–12 dKH

• Calcium: 400–450 ppm

• Magnesium: 1250–1350 ppm

• Nitrates: 5–10 ppm (slightly elevated levels are beneficial)

• Phosphates: 0.03–0.1 ppm ​

🥗 Feeding

While Trachyphyllia corals contain zooxanthellae, they benefit from supplemental feeding:​

• Foods: Mysis shrimp, brine shrimp, and other finely chopped meaty foods.

• Feeding Frequency: 2–3 times per week.

• Feeding Time: Best fed at night when the coral extends its feeding tentacles.

• Method: Use a turkey baster or pipette to gently direct food onto the coral’s tentacles.

⚠️ Considerations

• Aggression: Trachyphyllia corals can be aggressive and will sting other corals that grow or are placed too close.

• Conservation Status: Listed as “Near Threatened” due to habitat loss and over-harvesting for the aquarium trade. ​
